Siblings Harper and Dylan are reluctantly spending their summer at Camp Bigfoot. Run by an eccentric guy everyone calls Uncle Squatch, Camp Bigfoot is a classic summer camp with wooden cabins, forest trails, lots of outdoor activities-and the occasional Bigfoot sighting.

Uncle Squatch loves wearing a Bigfoot costume and trying to scare unsuspecting campers. But when a Bigfoot is spotted under a full moon, panic fills the camp. Is this Uncle Squatch's usual prank, or a real Bigfoot? Harper and Dylan are scared to find out!
