Paul discovers the hermit’s body floating in the reservoir, and realizes the infection is spreading through the water supply. Racing back to the cabin, Paul finds Marcy's remains and Dr. Mambo feeding on Karen. After killing Dr. Mambo with Bert's gun, he bludgeons Karen with a shovel out of mercy. A dying Bert returns to the cabin pursued by Dennis's father and his two companions. The posse shoots and kills Bert, and Paul kills all three of them. Paul looks for Jeff; he instead finds Grimm's corpse. Paul takes the convenience store's truck, and, while driving, discovers he is infected before hitting a deer. He reunites with Deputy Winston, who is partying with underage drinkers. Paul requests a ride to the hospital, but before the group departs, Winston is ordered to kill on sight several infected people on a killing spree. With the group turning on him, Paul attacks and infects several of Winston's friends before knocking Winston out. A passing truck drops off Paul at a hospital, where he weakly discusses where he caught the disease. The doctors inform the sheriff that Paul must be transferred. Lying in the back of Winston's squad car, Paul unsuccessfully warns him about the contaminated water supply; Winston dumps him at the edge of a creek.
