A group of teenagers go camping in a woods 10 miles out from the nearest town. As they pass through the town they notice that it is very quiet. They see an empty petral station and notice a light on. One of the girls suggest they should nip into the shop for some more alcohol. When two of the group members, Lauren and Joe get into the store they walk over to the fridge and get some beer. They look around the shop and see the till but no cashier. So they place the money on the till and begin to make there way to the door.
 They hear a creak and turn around to see an old man stood behind them and he begins to warn the two of them not to go out into the woods at night alone as something will happen. But they laugh and carry on walking back to the car. They tell their friends what just happened and Sophie becomes scared and begins to question whether they should still go camping or just go home. The other four laugh at her and call her a chicken. They get to the woods and set up their tents, it becomes dark very quickly so they all begin to search for some sticks nearby for their fire. They set the fire up and cook some of the food they have brought with them. As they are all sat around the fire, Harry gets his drugs out and offers them to the rest of the group but they all refuse. He goes off to the toilet further in the trees near a river. He begins to wee and hears some rustling in the bushes. He shouts at the person in the bushes assuming it's his friends and tells them to get lost. As he turns around to walk back to the camp he sees the person is still there looking at him. As he walks closer he notices it's not his friend and that it is someone wearing a mask. He screams and runs back to the camp with a bad leg after falling over a few times. He begins to tell them what he saw. But they all assume he is hallucinating from the drugs and go to bed.
In the middle of the night the wind is howling and the trees are rustling making Harry more scared. He gets out of his tent and intends to jump in Jack and Sophies but is interrupted on the way. The thing he saw earlier snatches him and slits his throat. Sophie wakes up and sees a dark figure stood outside the tent she grabs a pen knife and slowly looks out of the tent, as she does this the man grabs her hair and drags her out from the tent. Her screaming awakens Jack who runs out of the tent and jumps on top of the man telling Sophie to run. Scared for her friends safety she runs over to Lauren and Joes tent and sees they are dead, as she runs into the forest she notices a body who looks like Harry sat behind a tree. She runs over to him begging him to help Jack but as she shakes his body, his head falls off.
Meanwhile, Jack is being chopped up by the man in a mask. Once he is done he walks off into the woods with his axe in the direction that Sophie had ran. For a few minutes he chases her as she runs away building tension with music. As Sophie looks back to see where he is she runs into him who then begins to strangle her. But she hits him in the face and he lets go dropping her into the river where the current is strong.
She wakes up on the side of a large pond, covered in blood with no idea where she is.
