After 20 years on the run overseas, small-time ex-criminal Johnny Spitieri (Spit) slips back into Australia on a false passport only to find himself locked up in an Immigration Detention Centre with a massive target on his back as old enemies come looking for him, determined to settle old scores. As he struggles to stay one step ahead, the resourceful Spit finds new friends in detention, teaching them his version of mateship, and what it means to be truly Australian.
