Ben Wheatley directs this jet-black British comedy in which a romantic break turns into a bloody killing spree. Sheltered teenager Tina (Alice Lowe) accompanies her new boyfriend, 30-something misanthrope Chris (Steve Oram) on an 'erotic odyssey' - aka a caravan tour of the North of England. But unbeknownst to Tina, Chris harbours a dark secret: he is a serial killer whose explosive outbursts result in the violent deaths of any random strangers who happen to mildly inconvenience him. As the body count mounts, even the clueless Tina starts to suspect that her new boyfriend may not be quite what he seems.
