Theatrical version of Sony Playstation's "Until Dawn". A year after the mysterious disappearance of her sister Melanie, Clover and her friends travel to the remote valley where she disappeared in search of answers. Searching an abandoned visitor center, they find themselves stalked by a masked killer, murdered one by one... only to wake up and find themselves back at the beginning of the same evening. Trapped, they are forced to relive one night - only each time the killer's threat is different, each more terrifying than the last. Hope dwindles, and the group soon realizes they have a limited number of deaths left, and the only way to escape is to survive until dawn.
