Meet El, Erin and Joby – the Unholy Trinity.
They're typical teenagers – dabbling with Satanism, sex and Spar's finest vodka to an extreme metal soundtrack.
Up on the roof of El's Bristol flat they're reciting the lord's prayer backwards, perfecting chalk pentagrams and making black cloaks out of El's Mum's sheets – their rucksacks stuffed with black candles, cigarettes and cheap booze. When one of their rituals gets out of hand and El's dead father is invoked, family relationships and friendships get twisted up in the brewing chaos that follows.
Can they control the forces of darkness or will it all get out of hand? And what do you do when your Mum's as big a teenager as you?
