THE FINAL TERROR

A young couple named Jim and Lori lose control of their motorbike while riding in a forest. With Jim hurt, Lori finds no help and returns, only to find Jim dead hanging from a tree before she is killed by a trap. Weeks later, a group of campers consisting of Dennis, Margaret, Windy, Marco, Nathaniel, Boone, Eggar, Vanessa, Mike, and Melanie, arrive at the forest. The group makes a clearing and spend the night around a bonfire telling a story about a young woman who was raped and became insane, so she was put in a local mental institution, where she gave birth to a baby boy who was taken from her. When the boy was 19, he took his mother from the institution and released her to live in the forest.

The next morning, the group discover that Marco and Eggar are missing. While the others search for them, Mike takes a swim with Melanie and later they have sex, during which Mike is stabbed to death by a camouflaged killer who then kidnaps Melanie. Nathaniel and Dennis find an abandoned cabin containing an old grave. Dennis enters the cabin and Nathaniel hears him scream, only for it to be a prank by Dennis trying to scare him. While searching the cabin for food and items, they find a severed wolf's head in a cabinet and are shaken before returning to the camp.

That night, the killer appears near Margaret in her sleep and she hysterically tells the others what she saw. The campers also find Marco, who has returned to the camp. After Vanessa gets angry at the men for scaring the girls, she walks off alone to the outhouse; she screams when Mike's severed head falls onto her, and the group comes to her aid. The group spends one more night at the camp, and unsuccessfully search for Melanie who they assumed was still with Mike. In the morning they go to the cabin to look for the killer, unaware that he is down in the basement with a captured Melanie, and they flee with the rafts after finding a human hand in a glass jar. While rafting along the river, the body of Melanie is tossed onto the boat by the killer which causes panic among the group. Burying Melanie near the river, the group continues on to the end of the river and find their empty, broken-down bus. They spend the night there, but the killer attacks and gets inside the bus before the group escapes out the back door. Windy gets separated and is slashed by the killer, where the group comes to her and gives her first aid.

In the morning, the group gathers supplies and camouflages themselves. They find a knocked over redwood tree and devise an ambush on Eggar. Dennis climbs one of the highest trees, where he sets a spiked log trap. Marco begins calling out for Eggar, who appears and begins to strangle Marco with a rope. The group attacks Eggar, believing he is the killer. While Dennis is watching the rest of the group fight, the killer climbs out from the roots of the knocked over redwood tree. The killer slashes Dennis's ankle and he falls to his death. The killer rises up to scream; it is revealed that Eggar's missing, feral mother (the subject of the earlier story) is the killer. As she walks toward the group, she sets off the trap and is mortally wounded. The film ends with the group watching in horror as Eggar's mother hangs dead in the trap.

A group of teenage couples go to the forest in search of a romantic and relaxed weekend. But they are going to learn to survive in an unknown territory as a hunter comes after them. The hunter has set up many traps for his favorite kind of creatures: unexpecting humans.
