Sophie's 18th birthday becomes a bloodbath when monsters descend upon her house, devouring the guests and killing anyone who tries to leave. To survive the night, Sophie must face her destiny: monsters are real and she's the only one who can stop them.
The sole survivor of a blood-drenched massacre must team up with a rag-tag bunch of rookie cops and lawbreakers to defend a police station from an invasion of monsters from another dimension.
