Answer 7

Cabin Fever

The film centers on five recent college graduates, Jeff, Karen, Paul, Marcy and Bert, who trek to a remote cabin deep in the woods to celebrate with some wanton s*x and copious amounts of alcohol.

When they arrive Bert, the buffoon of the group, goes hunting, and accidentally shoots a sick man in the woods. They are also visited by a stoner camper, Justin (aka Grim), who has a large dog named Doctor Mambo.

Bert goes hunting, and accidentally shoots a vagrant in the woods. Although not apparently seriously injured, he is extremely ill with some unknown disease, and Bert leaves him to die. The man later turns up at the cabin, even sicker, asking for their help in seeking medical attention, but when he recognizes Bert, the group panics and turn him away without assistance. He attempts to steal their truck and in the scuffle Paul and Marcy accidentally set him on fire and he runs into the woods where he falls into the cabin's water supply.

When Karen drinks from the contaminated water, she becomes infected and results in a rapid onset of symptoms. Paul discovers her condition the next morning when he attempts to arouse her and finds that she is feverish, delusional and there is a huge piece of her leg missing. Unsure whether to take Karen for medical attention or wait out her fever, the friends cannot determine the best course of action. Fearful that the truck may be infectious, or that any one of them could be carrying the disease, they begin turning on one another. In order to "quarantine" Karen, they lock her in a tool shed.

As Karen lies in the shack getting sicker, her friends seek help from several sources, to no avail. They find a farm, where a woman offers to help them find a tow truck, but have to rapidly leave when they see a photograph and find that the vagrant they burned was her cousin Henry.

Jeff and Bert seem driven mad by the situation, and while Jeff thinks only of his own safety, Bert emerges as the responsible one and begins to fix their truck. Doctor Mambo, now vicious and possibly infected, returns without his owner and terrorizes the campers. Jeff sets out on his own with his uncontaminated supply of beer because of his fear of infection.

The other members of the group contract the disease by exposure to the tainted water and other ill people. Bert shows signs of infection after also drinking the water and drives to get help; during his trip he is hunted by the local townsfolk, who fear the disease he is carrying, and attempt to kill him to quell it.

Paul sets out to get help on foot and comes across the body of the drifter who carried the disease rotting away in the local reservoir, into which he falls due to a faulty ladder, and lands atop of the diseased corpse. He also finds the body of Grim in a cave, having either rotted in half or been torn in half by his own dog, Dr. Mambo. Marcy (who had drunk some of the contaminated water) shows signs soon after having a sexual encounter with Paul, and breaks out in huge lesions along her back and legs which she tries to wash away in the bathtub. Panic grips her and she runs from the cabin, but is chased down by the dog, Dr. Mambo, and savagely ripped apart.

Abandoned by everyone else, Paul returns to the shack in an attempt to finally take Karen for help. He runs right into Dr. Mambo and shoots the fierce dog. He finds Karen still alive but horribly mutilated by the disease and having been savaged by the dog. He realizes that there is no hope for her and puts her out of her misery with a shovel. Around this time a wounded and thoroughly infected Bert makes his way back to the cabin, and pleads for Paul to help him with the local hunters, Paul agrees. When the hunters find the cabin, they enter and shoot Bert, killing him, but Paul quickly kills all three.

Paul, newly infected by his fall into the reservoir, seeks a way into town. Taking the truck, he accidentally crashes into a deer whose kicking feet trap him in the truck, and he is covered in blood when he is forced to shoot it to escape. Continuing on foot, he comes across a party that has a deputy of the town in attendance. The deputy had promised a tow truck to fix their broken car days earlier, as Paul stumbles into the party, bloody and infuriated, the sheriff radios the deputy and informs him that a cabin of college kids have a disease and that they've killed several people; their orders are to shoot on sight. Paul attacks the partygoers in a rage and attempts to escape on the highway, where he is brought into town and dumped outside a hospital by a passing trucker.

The doctors realize they cannot treat him, and instruct the sheriff to take him to a larger hospital. The fear of further outbreak and Paul's earlier, violent run-in entices the sheriff to have Paul dumped in the woods and left to die. The deputy, whose party he ruined, obliges happily.

Jeff emerges from his alcohol-induced stupor and finds his way back to the cabin to discover i
