One year after her sister Melanie’s mysteriously disappeared, Clover and her friends go to the remote valley where she disappeared to find answers. By exploring the abandoned visitor center, they find themselves a mask killer and terribly kill one by one … Only to wake up and find themselves at the beginning of the same evening. Stuck in the valley, they were forced to survive again and again to survive a nightmare – only every time the killer threat is different, everyone is frightening than the last. I hope the group soon realizes that there are few deaths left, and the only way to escape is to survive until dawn.
