Boston, 1963. A city on the edge. The Boston Strangler has already claimed a dozen victims. For the three Daley brothers, crime is very much the family business but the Strangler's murderous spree is about to bring violent death a lot closer to home: Joe - tough-talking cop whose gambling habits - fast women, slow horses - drag him down into the city's gangland. Michael - Harvard-educated lawyer, tasked to bring the Strangler to justice. Ricky - expert burglar and the devil-may-care youngest son who is used to leading a charmed life. When the Strangler strikes, they will all be forced to look into their family's own lethal secrets and the one death in the past that has changed them forever.
