The screenplay follows Charles and Fred, employees at a mental hospital. A man is seen exiting a cabinet on the security camera. When Charles and Fred investigate, they discover the cabinet leads to a series of strange, constantly changing hidden rooms. When they open the cabinet again, an unknown man in a black robe and pale mask emerges, offering to "fix" Fred with an unknown "cure".

2. INT. MENTAL HOSPITAL MAIN LOBBY - NIGHT
An old wooden door CREAKS open, CHARLES steps out of his
office and marches towards the front desk.
CHARLES
Fourth one this week, Fred. I think
we’re gonna need to check all of
the others, just to be sure.
FRED
Should I alert the, uh.. Y’know?
CHARLES
No, no, let’s keep this quiet until
we know what we’re dealing with.
Arrange for the patients to be
examined in the morning.
CHARLES turns around and walks sluggishly towards his
office. FRED looks down at the security monitor, his
expression turns to confusion.
FRED
Hey uh.. Charles? Come look at
this.
CHARLES
Huh? What is it?
CHARLES walks behind FRED’S desk and looks at the monitor.
FRED
Some guy, just... just walked out
of the cabinet in the storage
room...
CHARLES
Who is this guy? He’s not staff,
and he doesn’t look like one of the
patients.
FRED
I dunno man. I think you should
check this out, I’ll keep an eye on
the camera.
CHARLES
Nope, you’re coming with me.

INT. STORAGE ROOM - NIGHT
CHARLES and FRED slowly open the storage room door with a
CREAK. As they enter, FRED flicks on the light switch.
CHARLES looks around.
CHARLES
I don’t see him. Check the cabinet.
FRED walks up to the cabinet and quickly pulls it open.
FRED
What the... Charles... I think I
know how that guy got in.
CHARLES runs over to FRED and looks into the cabinet.
CHARLES
What is this? Some sort of secret
entrance to a hidden room in this
building?
FRED
I don’t know. But I’m not going in
there. We can just lock it and tell
the higher-ups about this and let
them deal with it.
CHARLES
No, they probably know about this
already, they have to know! I bet
they’d fire us, or worse, if we
told them. I’m gonna go in and look
for that guy.
FRED SLAMS the cabinet shut.
FRED
No man, I don’t think you should do
it.
CHARLES opens the cabinet again.
CHARLES
I’m gonna go in, with or withou-
This is different.
CHARLES and FRED stare into the cabinet.
FRED
It didn’t look like this the last
time... Uh, close and open it
again.
(CONTINUED)

4. CONTINUED: 3.
CHARLES slowly shuts the cabinet door as FRED stares through
the gap, then pulls it back open.
FRED
What? How? It’s different again,
this new room looks like it’s made
of... Flesh..
CHARLES
That’s disgusting. Next room.
CHARLES slams the door shut and pulls it open again. A man
steps out of a room plagued with shadow. He is wearing a
black gown/robe, and a pale white mask.
The unknown man turns to FRED.
UNKNOWN
I sense it within you. I assure
you, my cure is quite effective. I
will fix you.
