Meet Jamie. He's your average London teenager: school, nagging parents, that girl down the road - he's got everything, but he's about to lose it all. It's Christmas, 2012 - the decorations are up, and there's a chill in the air. There's something wrong out in the streets, but Jamie ignores it. It's the biggest night of his year, the night that he's going to get with Frankie, the night it's all going to happen. Except his parents want him to stay home. And so Jamie has to get creative. He'll get his night out. Unfortunately for him, this night also happens to be the last date on the Mayan calendar. And that can mean only one thing: Apocalypse.
