A year after her sister Melanie’s mysterious disappearance, Clover and her friends travel to the remote valley where she vanished in search of answers. While exploring an abandoned visitor center, they find themselves being stalked by a masked killer and are horribly murdered one by one… only to wake up to find themselves back at the beginning of the same night. Trapped in the valley, they are forced to relive the nightmare over and over again – only each time the murderous threat is different, each more terrifying than the last. As hope fades, the group quickly realizes that they have a finite number of deaths left and the only way to escape is to survive until dawn.
