Charlie's rave parties are crazy - and tonight's rave will be her most extreme yet. Her oversexed friends throw back the drinks and start setting up, unaware that they're being watched by a sinister being lurking within the shadows of the huge warehouse. With their attention diverted from the party and onto each other's bodies, they begin to disappear into the night. With the music blaring, no one can hear their frenzied cries of passion - and terror. Little do they realise, a beastly presence resides in this place, dragging a mammoth, inhuman weapon that serves only one purpose: to kill all who trespass there. Charlie hoped tonight's party would be the best ever... will it be her last?
