Angry and defiant, thirteen-year-old Devlin believes he's unwanted. His younger siblings, who have been in foster care, are now back home with his mother, who is in an abusive relationship. He's fed up with changing schools and foster homes, and decides to run away from his foster-uncle's farm. But then he meets a horse about to become 'dog tucker' and becomes involved in the harness-racing scene, where he is instrumental in unravelling a deception.
