Synopsis: This novel fusion of car-chase film and spooky horror became a surprise box-office hit in 1975. The story begins with car enthusiasts Frank (Warren Oates) and Roger (Peter Fonda) taking their wives, Kelly (Lara Parker) and Alice (Loretta Swit), on a vacation in a recreational vehicle. Their camping trip goes horribly awry when Frank and Roger accidentally stumble upon a group of hooded cultists committing a human sacrifice.
