In Hackney in 1977, Johnny Jarvis and Alan Lipton become unlikely friends in their final year at school: Jarvis is the class clown, a popular lad with a talent for welding, while Lipton is a bookish dreamer who spends his time fabricating impressive exploits, pondering the future and fantasising about the father he's never met. As they leave school and anxiously embark on an uncertain future, can their friendship survive?
