After fixing the truck, Bert coughs up blood but does not tell the others. Bert drives off after Paul and Jeff discover he has caught the disease. Jeff takes the remaining beer and leaves, terrified of becoming infected. Bert seeks help at a convenience store but angers the owner after his son, Dennis, bites him. Bert flees, chased by Dennis's father and two friends. At the cabin, Marcy worries that they will all contract the disease. When Paul comforts her, they impulsively have sex. Regretting the affair, Paul leaves while Marcy takes a bath, crying; as she shaves her legs the flesh begins to peel off and she runs outside in a panic, where she is eaten alive by Dr. Mambo.
