Hollow Man.

 "Hollow Man."  

Inside a military-sanctioned research lab, 

a rat inadvertently scurries into a cage in  

search of food and water, but instead of finding 

sustenance, it becomes prey to an unseen predator.  

The invisible beast only becomes perceptible 

when the rat's blood taints its sharp fangs.

Elsewhere, Dr. Sebastian Caine works overtime 

in his apartment to develop a formula to reverse  

a procedure that turns a subject invisible. 

He stops for a while to admire his alluring  

neighbor in the next building as she changes 

her clothes. Sebastian's anticipation of seeing  

her undress turns to disappointment when the 

woman shuts the blinds on her bedroom window.  

As he paces around the apartment, he suddenly 

comes up with a breakthrough, so he immediately  

tests it on the computer. Not long, he calls 

his colleague and ex-girlfriend Linda McKay  

to report his success. During a video call, he 

notices a man on Linda's bed and asks who it is,  

but Linda turns the camera away from the 

bed, noting that her love life is no longer  

Sebastian's business. After showing Linda the 

breakthrough formula, he asks her to call their  

colleague Matt Kensington to prepare the gorilla 

Isabelle so that they could conduct a live test.

After dropping the call, Linda wakes up Matt 

and tells him that they have to go to the lab  

immediately because Sebastian finally cracked the 

reversal formula. Linda tells him that they should  

go in separate cars to keep their relationship a 

secret from Sebastian. Matt hints that they will  

have to let Sebastian know at some point, so 

Linda assures him that she will do it someday.

Upon their arrival, Matt goes straight to 

Isabelle's cage to sedate the invisible gorilla,  

but before he could inject her with the solution, 

the animal scratches him and runs out of the cage.  

As Matt chases the ape, he runs into Sebastian in 

the hallway. After grabbing a tranquilizer gun,  

Sebastian initiates a $10 wager, saying 

he'll be the one to get Isabelle first.  

With the gorilla cornered, Matt shoots 

her with the tranquilizer, but he misses.  

Sebastian immediately follows up with one shot 

and hits the ape, knocking her unconscious.

Dr. Sarah Kennedy, the lab veterinarian, suddenly 

barges in and confronts Sebastian about injecting  

the new formula into Isabelle without even 

testing it. Sebastian argues that skipping the  

tests will save them time. Linda interrupts their 

argument to tell Sebastian that the lab is ready.

After checking Isabelle's vitals, Sarah 

sprays the gorilla's arms with a dye and  

taps it to prepare for the injection. As Matt 

prepares to inject Isabelle with the serum,  

Sebastian grabs the syringe from Matt, saying 

the honor should go to him. Soon after injection,  

the serum travels through the ape's 

veins and makes its way to the heart.  

The research team watches in amazement as 

Isabelle's vital organs become visible.  

However, the gorilla starts thrashing around in 

pain as her blood pressure and heart rate rise.  

Soon the ape starts going through cardiac arrest 

and eventually flatlines, so Linda hits her with  

the defibrillator several times. Sebastian asks 

Matt to administer an intracardiac injection after  

getting no response, but before Matt could inject 

the gorilla, her heart starts beating again.  

As her condition stabilizes, 

Isabelle's body slowly becomes visible.

The research team celebrates their success 

by dining in an upscale restaurant.  

During a moment alone with Linda, Sebastian 

reminisces about their failed relationship and  

hints that he wants to get back together with 

her. However, his hopes of rekindling their  

relationship are soon dashed when he notices 

her pulling back when he tries to kiss her.

Days later, Sebastian meets with an oversight 

committee at the Pentagon to report his findings.  

But Linda and Matt are surprised to hear Sebastian 

telling them that he was unsuccessful at reversing  

the procedure. Sebastian tells the committee that 

the research team is close to finding a solution,  

but they still need more time. Dr. Howard 

Kramer, Sebastian's former teacher,  

praises his ingenuity and determination, but 

he warns Sebastian that the government can  

easily replace him if he doesn't 

show them any results soon.

Sebastian tells Linda and Matt that he wasn't 

ready to let the military know about their  

success, fearing that the government will take 

over the project once they report their findings.  

Sebastian suggests conducting a test on 

humans without letting the government know.  

Matt reminds him that there are rules 

and procedures, but Sebastian argues that  

following the rules will get them nowhere. 

Sebastian assures them that they will have  

a better chance of winning the Nobel Prize 

by taking the project into their own hands.

When they get back to the lab, Sebastian 

tells the rest of the team that they got the  

clearance to go ahead with human testing because 

he volunteered. Sensing the team's apprehensions,  

Sebastian reminds them that they had successfully 

brought back seven apes in the past four weeks.  

He stresses that human testing 

would be the next logical step  

if they want to keep the project going. 

Once they go through with the procedure,  

Sebastian will stay invisible for three 

days before performing the reversal.

On the day of the procedure, Matt tells Sebastian 

that he can still back out, but Sebastian is  

determined to be the first human test subject 

for his experiment. On the operating table,  

Sebastian takes the serum from Linda, saying 

he'll inject himself so Linda won't be blamed  

if anything goes wrong. Soon after shooting the 

serum into his vein, Sebastian starts feeling  

a tingle in his arm. He suddenly starts thrashing 

around from the pain as his skin starts to vanish.  

Seeing his unstable heart rate, Carter 

Abbey, the emergency medical technician,  

immediately brings the defibrillator beside the 

operating table. But before they could shock him,  

his heart rate begins to stabilize 

even as he writhes from the pain.  

Soon, Sebastian loses consciousness 

while his body slowly turns invisible.

After 17 hours, Sebastian finally wakes 

up. Overwhelmed by the brightness,  

Sebastian tells Linda to turn off the lights, 

noting that he can't shut his eyelids. Linda  

points out that Sebastian can still see when 

he shuts them because they are now transparent.  

Sebastian immediately walks to a mirror to 

see if he has really turned invisible. He  

then walks with Matt and Linda to the lab to let 

the rest of the team marvel at his invisibility.

Later on, Linda informs Sebastian 

that one of the team members will  

be staying with him if he needs anything. 

The rest of the team will be on alert so  

that they could run back to the lab 

within 30 minutes. Before leaving,  

Linda tells Sarah that Carter will come by at six 

in the morning while she will be back by eight.

While Sarah sleeps, Sebastian approaches her and 

caresses her hair, trying to find out if she's  

awake. Not long, Sebastian starts unbuttoning her 

shirt and touches her inappropriately. When Sarah  

wakes up, she notices her unbuttoned shirt, so 

she asks Sebastian if he's in the room with her.  

When she looks at the monitor, Sebastian is 

not in his bed, but he gets back and lies down  

as soon as Sarah turns around. The following 

morning, Sarah tells Linda and Matt about her  

suspicion that Sebastian had done something to 

her while she was asleep. However, Sarah tells  

them not to confront Sebastian because she is 

still not sure if anything happened. When Matt  

asks Sebastian about his absence from his room, 

Sebastian explains that he went out to get coffee.

Three days after the procedure, the team prepares 

Sebastian for the reversal. After Matt injects  

him with the serum, Sebastian starts breathing 

heavily, telling them that something is wrong.  

Soon, he thrashes around the table and breaks free 

from the straps, so Matt and Carter hold him down.  

However, Sebastian still manages to get up from 

the table after throwing Carter across the room  

and kicking Matt in the face. His body 

becomes visible for a moment, but he  

drops to the ground and becomes unconscious. 

By the time they bring him back to the table,  

Linda discovers that Sebastian no longer 

has a pulse, so Matt performs C.P.R. on  

him. His pulse eventually returns, and 

his body slowly becomes invisible again.

When Sebastian wakes up hours later, 

Linda tells him that he almost died.  

Sebastian tells Linda that he needs to make some 

adjustments if he's going to remain invisible,  

so they make a latex mask to make him visible as 

he walks around the lab. Over the next few days,  

Matt desperately tries to figure out how to 

reverse the procedure without killing Sebastian.  

After ten days of invisibility, Sebastian 

becomes frustrated from undergoing several  

tests and being confined to the lab. One 

night, he decides to go out when Carter  

is the only one at the lab watching 

over him. Failing to stop Sebastian,  

Carter immediately calls the other team members 

to alert them about Sebastian's departure.

While driving on the road, he decides to have 

fun with two kids in a car by showing them his  

empty eye sockets. Linda asks Matt to go to the 

lab while she checks out Sebastian's apartment.  

When Sebastian gets home, he notices his neighbor 

at the next building changing her clothes.  

He hesitantly decides to take advantage of his 

invisibility and go to the next building to  

see the woman up close. Sebastian rings the bell 

several times until the woman opens the door and  

comes out of the room. When she gets back inside, 

Sebastian observes the woman combing her hair.  

He then moves the mirror several times, causing 

the woman to look around the room in a panic.  

As she turns away from him, Sebastian 

starts forcing himself on her.

Linda soon arrives at Sebastian's apartment 

and finds his mask and clothes on the bed.  

After having his way with his neighbor, 

Sebastian looks out the window and sees  

Linda in his apartment. He waits until 

Linda leaves before returning to his home.

Back at the lab, Frank Chase, the lab 

technician, hands out tranquilizer guns  

to the rest of the research team as they 

prepare to look for Sebastian outside.  

Sebastian soon arrives and tells them that 

he only went home to pick up a few things.  

Linda tells him that she'll go straight to the 

committee if he tries leaving the lab again. Linda  

tells Matt about her concern that the invisibility 

has now started to affect Sebastian's mind because  

he has been invisible far longer than the animals. 

While Carter performs some physical tests on him,  

Sebastian confesses that he messed with a 

woman while he was outside, and he liked it.

A few days later, Matt calls Linda to tell 

her that he had a breakthrough. However,  

the process breaks down during a simulation at the 

lab. Sebastian expresses his frustration to Linda  

that he cannot take advantage of his invisibility, 

adding that he has become a prisoner at the lab.  

When Linda tells him that he's not a 

prisoner, Sebastian points out that  

Linda can freely go outside and be with 

her boyfriend while he's stuck in the lab.

Later that night, Sebastian grabs a piece of 

electronic equipment at the lab and installs  

it in the camera inside his room to run a 

video loop of himself sleeping on the bed.  

He decides to visit Linda's apartment and 

finds out that she's been dating Matt.  

As Matt and Linda begin to make love, Sebastian 

breaks the window next to the bed, interrupting  

them. Linda calls the lab to find out if Sebastian 

has escaped, but Frank tells her that he's in bed.

Sebastian goes back to the lab, enraged with 

jealousy. While pacing around the facility,  

he gets annoyed by the 

barking of the invisible dog,  

so he grabs it and slams it on the 

walls of the cage until it dies.  

When Sarah confronts Sebastian about the dead 

animal, he claims to be asleep when it died.  

After going through the video security footage, 

they conclude that Sebastian never left the room.

While Linda is working at home, she's suddenly 

disturbed when she hears noises all over the room,  

so she runs to the lab to see if Sebastian's 

there. Linda sees him lying in bed on the video  

monitor, but she doesn't find him in his 

room. She realizes that he's been running  

a video loop of himself in bed, so she calls 

everyone in the team to get back to the lab.  

Meanwhile, Sebastian walks around the parking 

lot, observing the research team as they arrive.

Matt and Linda visit Dr. Kramer to report 

Sebastian, but unbeknownst to them,  

Sebastian followed them there. After 

they leave, Sebastian attacks Dr.  

Kramer by the pool and drowns him. Dr. 

Kramer calls out to his wife for help,  

but by the time she gets to the 

pool, Dr. Kramer is already dead.

When Linda arrives at the lab the next 

day, she tries to call Dr. Kramer,  

but she finds out that he drowned in the pool 

the previous night. She tries calling another  

member of the oversight committee, but 

the phone lines are suddenly disconnected.  

Matt and Linda try to leave the lab, but the 

security system won't let them use the elevator.  

Soon, the research team learns that their 

access codes inside the lab have been revoked.

As the team starts searching for Sebastian, Janice 

Walton, the lab tech, falls behind while she grabs  

a thermal goggle. Sebastian suddenly appears at 

the door and strangles her with an I.V. line.  

She screams, but her voice is drowned out by the 

noise of the screeching animals in their cages.

Failing to find Kramer, Linda uses the intercom 

to tell Sebastian that the committee already  

knows what he did. But Sebastian reveals 

that he killed Kramer the previous night  

before he could tell anyone about him. 

Soon, the team realizes that Janice is  

missing. Using their thermal goggles, they 

discover her lifeless body inside a locker.  

Linda asks Frank to restore their access codes 

so that they can activate motion detectors.

When they see someone moving through the 

corridors, Matt and Carter arm themselves  

with tranquilizer guns to find Sebastian as 

Linda guides them. Carter sees heat signatures  

behind the pipes, but Matt discovers 

that the heat is coming from the vent.  

While Matt is not looking, Sebastian grabs 

Carter while hiding on a ceiling pipe.  

Matt shoots him, but he misses and hits a 

pipe instead. As Matt continues to shoot,  

Sebastian flings Carter toward the wall. Carter 

hits the corner of a metal box by the pipes,  

cutting a major artery and 

causing massive blood loss.

Sebastian surrounds himself with 

heat emanating from the pipes,  

rendering Matt's thermal goggles useless. After 

running out of tranquilizers, Matt grabs a fire  

extinguisher to use it against Sebastian. 

With the smoke from the fire extinguisher,  

Matt is able to see Sebastian, but he still 

struggles to hit him. Sebastian knocks Matt  

to the ground with a punch and a kick, 

but Linda arrives to take him to safety.

Sarah learns that Carter has lost a lot of 

blood, so she grabs several bags of blood  

from the walk-in fridge. Before she could 

get back to Carter, Sebastian locks her in,  

so she splashes the blood all over the floor to 

see Sebastian's footsteps. She manages to douse  

Sebastian with blood, but Sebastian tackles 

her and shoots her with the tranquilizer gun.  

Not content with knocking Sarah unconscious, 

Sebastian breaks her neck, killing her instantly.

Carter soon dies from severe blood loss 

while Frank waits for Sarah to get back.  

Frank leaves Carter's dead body behind and 

goes with Matt and Linda to find Sarah.  

When they discover her body in the walk-in fridge, 

Sebastian emerges and stabs Frank with a crowbar.  

Afterward, Sebastian stabs Matt with a metal bar 

in the lower chest and locks him and Linda inside  

the fridge. Sebastian goes back to his room 

to wear his mask and prepare to leave the lab.

Linda patches up Matt's wound with duct tape 

and escapes from the fridge using a magnetized  

metal drawer handle. She then drags Matt out of 

the freezer and lights a fire to warm him up.  

Meanwhile, Sebastian gathers up some 

chemicals to create an explosive to  

blow up the lab and cover up his 

crimes. He puts the chemicals in  

a centrifuge and sets the timer for five 

minutes before heading to the elevator.  

Upon reaching the lift, Linda stops him and sets 

him ablaze with a flamethrower. She slides down to  

the floor to stop the elevator doors from closing 

and continues shooting flames at Sebastian.

After walking out of the lift, Sebastian slowly 

peels away his singed clothes, making him  

invisible again. Linda uses the remaining fuel 

on the flamethrower to activate the sprinklers.  

Sebastian manages to sneak up on her and subdue 

her, but Matt comes to her rescue, knocking  

Sebastian out with a crowbar. Sebastian tries to 

hit Matt with the crowbar, but Matt fends him off,  

causing him to hit a fuse box. As Sebastian gets 

electrocuted, his body becomes partially visible.

Matt and Linda discover the makeshift 

explosive that Sebastian made,  

so they run to the elevator in the hopes 

of climbing the ladder that leads outside.  

As they climb up, the makeshift bomb 

explodes, sending the elevator upwards,  

scraping Linda's shoulder. The elevator is then 

pulled back down, but it stops just before it  

hits Matt. As they start climbing the ladder 

again, Sebastian pulls Linda back down. Linda  

and Sebastian fall on the elevator, which is 

hanging only by a thick wire. As Linda struggles  

to break free, and Sebastian steals one last 

kiss, telling her that it's for old time's sake.  

While they kiss, Linda grabs the wire holding up 

the elevator and uses her foot to disconnect it.  

Linda hangs onto the wire as she watches Sebastian 

fall to his death down the elevator shaft. Linda  

and Matt soon emerge from the burning building 

as firefighters scramble to put out the flames.

Before Sebastian turned invisible, the research 

team managed to tolerate his arrogance and extreme  

competitiveness. More of his bad qualities seemed 

to turn up soon after becoming the test subject of  

his own experiment. He immediately mistreated 

Sarah the first night he became invisible.  

When the reversal procedure failed, he grew 

agitated from being confined in the lab,  

so he decided to break protocol and 

leave. With no one to stop him outside,  

he takes advantage of his invisibility 

and assaults his neighbor.

Sebastian's obsession with Linda also grew 

out of control throughout the experiment.  

Although he's not in a relationship with Linda, 

he killed an innocent dog in a jealous rage when  

he discovered her relationship with Matt. Out 

of all his bad traits, the deadliest so far  

has been his ambition. In an effort to preserve 

his career, he killed his mentor Dr. Kramer, and  

he created an elaborate plan to blow up the lab, 

with all his colleagues trapped inside, to destroy  

all the evidence of his crimes. If it wasn't 

for Linda and Matt, he might have succeeded.
