Cabin Fever

A group of five college friends rent a cabin in the woods for a week-long vacation, only to succumb to an infectious flesh-eating disease after a hermit named Henry is accidentally shot by Bert and later attacks Paul. The infected man eventually kills Karen and Marcy, while also infecting others through bites and contact with his blood. As the group tries to survive, they are stalked and killed by Dr. Mambo, a Belgian Malinois dog that Grim had brought along, leading to a desperate fight for survival.
