Mitch Sewell's boxing career was just taking off when the unimaginable happened. He killed someone in the ring. Vowing never to step foot in a boxing ring again, he retires to run the gym he part owns and teach self-defence classes. Every day is a constant battle against the memories crippling him. That is until the day someone walks through the gym door and gives him a brief glance of how different his life could be, if only he can overcome his baggage. Can Mitch break away from the guilt, or will it keep him chained forever?
