Billy Sloane's school principal describes him as sloppy, shoddy, unpunctual, and uncooperative, but also infuriatingly truthful. Things aren't going to well for Billy, though. It's exam time at school and his mother is dying in hospital. His father has taken in a lady 'friend' to look after him and the police are looking for his brother Jack in connection with a string of armed robberies. The only bright light in Billy's life is a sick pigeon he has found and is caring for. At least it's something he can write passionately about in his English exam. But then he's pulled out of class to be grilled about his brother by a detective. Billy's honesty is about to be put to the test.
