24/33
A year after her sister Melanie mysteriously disappears, Clover and her friends head to the remote valley where she disappeared in search of answers. Exploring an abandoned visitor center, they find themselves being stalked by a masked killer and horribly murdered one by one… only to wake up and find themselves back at the beginning of the same series. Trapped in the valley, they are forced to relive the nightmare over and over again — only each time the criminal threat is different, each more terrifying than the last. With hope fading, the group soon realizes that they have a finite number of dead left, and the only way to escape is to survive until dawn.
