Rick adores his girlfriend, Bert, and is willing to go on a long hike with her into the remote mountain wilderness, following the trails around Fern Lake, even though that's the last place on Earth he'd want to be. Horrible memories of a long ago similar trip with his parents still torment him. Gillian, a successful businesswoman, is also on vacation, but her entertainment is clearly stranger than that of Rick and Bert. She likes to break into other people's houses and live there while the owners are away. It's a pity that she chose the home of a serial killer - especially a vile one who likes to take his victims into the wilds of Fern Lake so that no one will interfere with his fun. Soon our heroes will cross paths... Rick and Bert have no idea how wild it can be wild land. But they are about to find out...
