Scene-tropical forest . Tall trees. Two friends Krissy and Mica are in the forest.
Mica is pulling Krissy through the trees
Mica: Come on! Don’t be so gloomy…. This is supposed to be fun.
Mica lets go of Krissy and spins with her arms out while laughing with glee. Mica turns and grabs Krissy by the wrist again
Mica: Lets got this way!
She drags Krissy through the trees. Krissy appears alarmed
Krissy: Where are we going? I thought we were going to see Tristan?
Krissy’s brown hair flies behind her and Mica’s blonde ones bounce. Mica smiles
Mica: We are- but we’re in a tropical rainforest-. Obviously we’re exploring first
Krissy: Fine. (smiles) Race you to the fat tree!
They race and Krissy beats her easily. They stop at the tree out of breath
Krissy: (Heavy breathing) Beat you, ha! Cool! There’s a cave behind you!
Mica: (smiles) What?
Krissy: (she points) A cave. Behind you. Look!
Mica turns and they both observe the cave. It is old, grey and dark. Moss is growing on the cave walls. The cave is spooky. Mica looks unnerved. Krissy is curious. Human groans of pain can be heard.
Krissy: (bites her lip and smirks) Should we go in?
Mica: (shocked) What! No! Kri-
Krissy: Ok then… (pauses and smirks again) Let’s go in
Krissy eagerly climbs up the steep hill to the cave
Mica- (crosses her arms- annoyed) Krissy!
Mica sighs and follows her reluctantly
They are at the entrance of the the cave. It is very dark. Teenage boy is bleeding out from his arm in pain. Krissy runs toward him.
Krissy: What the hell happened to you? She bring out a thick blanket from his bag and presses against the wound.
Micha: Better question- who are you?
Boy groans in pain
Boy: Shut up and arm yourselves- there should be guns in my bag
A very exhausted looking Tristan comes into the cave. He has scars on his face and is armed with guns.
Tristan (looking grim): You guys shouldn’t have come. Here take these…
He throws the girls a gun each.
Krissy: Tristan. Why didn’t you tell us? We came to see you today. You said-
Tristan (annoyed): Sorry. I didn’t exactly have time to text in middle of trying to keep people alive.
Micha: Are you feeling alright? I think what’s best is that we all get the hell out of here and get that one to a hospital.
Tristan: You’ve come into the forest. Now there’s no getting out.
Micha: What?
Tristan exhales as if trying to figure out and explain the situation
Tristan: The forest is quarantined. There’s an epidemic… kind of….
Krissy: That no one else is aware of
Tristan nods and nibbles on his lip.
Tristan: It’s complicated.
Micha: And what are you killing?
Boy: It’s complicated…
Krissy drops to the floor and starts to seize.
Tristan (remains calm) : Micha did you guys happen to cross the river when coming here?
Micha nods in silence and panic.
Tristan (looks worried and  loads a gun): God, no. She infected. Get ready- they should be coming any moment now.
