An innocent camping weekend turns into terror and murder for four university students.  Henry Chatwell stalks, tortures and kills his wife's lover, witnessed by the students.  Unable to contact the sheriff, they return to their campfire, where they are taken captive.  Chatwell's verdict is that the students must die!  As the action unfolds, the students escape and are recaptured, one by one.  Except for Roger, whom Chatwell attacks with an axe, and the fight is on!
