MC’s hamster dies so his friends are going to take him camping to cheer him up, but they all ditch him and he goes alone. A couple rudely puts their tent next to his and gets murdered, but the killer spares MC because MC can’t entirely keep his face straight between excitement at living horror flicks and terror at being killed. Killer wears a bag on his face cause of past trauma, and kills to provide a cannibal food. Happy ending.
