Five teenagers head off for a weekend at a secluded cabin in the woods. They arrive to find they are quite isolated with no means of communicating with the outside world. When the cellar door flings itself open, they of course go down to investigate. They find an odd assortment of relics and curios, but when one of the women, Dana, reads from a book, she awakens a family of deadly zombie killers. However, there's far more going on than meets the eye.

Four Jack-the-lads find themselves heavily - seriously heavily - in debt to an East End hard man and his enforcers after a crooked card game. Overhearing their neighbours in the next flat plotting to hold up a group of out-of-their-depth drug growers, our heros decide to stitch up the robbers in turn. In a way the confusion really starts when a pair of antique double-barrelled shotguns go missing in a completely different scam.
