Fourteen-year-old Calum Brooks has big dreams. One day he'll escape this boring life and write movies -proper ones, with massive budgets and A-list stars. For now, though, he's stuck coping alone while his dad works away, writing scripts in his head and trying to stay 'in' with his gang of mates at school, who don't like new kids, especially foreign ones.
But when his father invites his new Polish girlfriend and her son, Sergei, to move in, Calum's life is turned upside down. He's actually sharing a room with 'the enemy'! How's he going to explain that to his mates? Yet when Calum is knocked down in a hit-and-run and breaks both legs, everything changes.
Trapped at home, Calum and Sergei slowly start to understand each other, and even work together to investigate a series of break-ins at the local community centre. But Calum can't help feeling that Sergei's hiding something. Is he really trying to help, or to cover up his own involvement in the crime?
