Four teens get some scary surprises when they camp out at Finland’s Lake Bodom, the site of a grisly massacre back in 1960. With the killer still at large, the teens have plenty of time to theorize about who might really be responsible and if he’s still out there. Right on cue, when the kids tuck in, footsteps start approaching and a killer emerges. But though director Taneli Mustonen wants you to think you know where the story’s going, he’s got some very clever twists on deck that take the story in an even more shocking direction. A SHUDDER EXCLUSIVE.
