In the late 1970s, The Outfit has the entire city of Chicago in its hands. Tony Accardo is its fearless leader. Nicky Passero is his loyal soldier, though no one knows he has a direct line in to the boss of bosses. When the Christmas gift Accardo got for his wife, an inscribed bracelet with gold and diamond inlay, is stolen along with other items in a jewelry heist, Nicky is charged with tracking down and returning all of the items --- by whatever means necessary. Forced into an impossible situation, Nicky must find a way to carry out Accardo's increasingly unhinged instructions and survive the battle for control of Chicago. What Accardo doesn't know: Nicky has a secret that has made his life impossible and has put him in the pocket of the FBI.
