A small town beside a mountain is getting ready for spring break. Wade has been searching for his brother Shredder, who disappeared on the slopes with his friend Hucker. He and his girlfriend Madison ask Dale, who patrols the ski runs, to organize a rescue, and Dale turns them down. At a party that night, an old man called Duffy bursts in and says he has seen sharks in the snow. Diana, the sheriff's wife, tells her husband that she saw the sharks when she was young.
