Jamie Lancaster is the sole survivor of a bloody massacre at a remote cabin in the woods. Claiming her friends were torn apart and eaten by a horrific monster, she’s arrested and locked up for a crime she didn’t commit. But Jamie’s assertion of innocence was real because, suddenly, the entire police station is ripped from reality and thrown into a nightmarish dimension of Lovecraftian monsters hungry for human flesh. To survive the night, Jamie must team up with rookie cops and lawbreakers to slash their way through a monster army and find a way to get back home.
