When ex-junkie, Johnny (Spit) Spitieri, flies into Australia on a false passport, he is locked up in an Immigration Detention Centre . The authorities want to know who he is, and where he's been. But so does gangster Chicka Martin, and his crooked cop mate, Arne Deviers, who are hot on Spit’s trail, and the Independent Public Integrity Commission is convinced the bumbling amnesiac is really an unlikely criminal mastermind. As Johnny talks up a storm without saying anything at all, he makes new friends amongst the detainees, and teaches them his version of mateship, and what it means to be truly Australian.
