Two young private bankers, Alistair and Jamie, who have the world at their feet, get their kicks from playing a 12 hour game of hunt, hide and seek with people from the margins of society. The next target is Sean Kelly, a parentless teenager who lives with his sister on a housing estate on the outskirts of Edinburgh. She's in debt, he is going nowhere fast. Sean agrees to play for cash. He soon realises he's walked into twelve hours of hell where survival is the name of the game.
