The group gathers around a campfire that night, where they are joined by a friendly drifter named Grimm and his pet dog, Dr. Mambo. When it rains, Grimm leaves with his dog to pack up his belongings. While the friends wait for Grimm indoors, the hermit returns, begging for help. When Bert shuts the door on the sick hermit, he tries stealing the group's car while vomiting blood. When the hermit approaches Marcy and Karen, Paul accidentally sets him on fire. While seeking help the next day, Jeff and Bert encounter a butcher but leave after learning she is the dead hermit's cousin. Paul receives assistance from police Deputy Winston, who promises to send up a tow truck. Paul tries comforting Karen, who is upset over the killing of the hermit. After calming her down, Paul attempts to have sex with her; as he reaches between her legs, he discovers an infection that has spread in her groin. The group isolates her in a shed.
