1979. Lawyer Giorgio Ambrosoli is appointed liquidator of Banca Privata Italiana, the empire of mighty financier Michele Sindona. Teaming up with unassuming cop Silvio Novembre, Ambrosoli uncovers the real scope of Sindona's malpractice, exposing him as the middleman in a global network linking the Sicilian Mafia, Italy's ruling Christian Democrats, and CIA-backed covert operations across Western Europe. Isolated by his own government and pressured by mob hitmen, Ambrosoli refuses to back down, insisting he is simply 'doing his duty'.
