Based on the true story of would-be Brooklyn bank robbers John Wojtowicz and Salvatore Naturile. Sonny and Sal attempt a bank heist which quickly turns sour and escalates into a hostage situation and stand-off with the police. As Sonny's motives for the robbery are slowly revealed and things become more complicated, the heist turns into a media circus.

After serving 28 years in prison for accidentally killing the son of a crime boss, newly paroled gangster Val reunites with his former partners in crime, Doc and Hirsch, for a night on the town. As the three men revisit old haunts, reflect on their glory days and try to make up for lost time, one wrestles with a terrible quandary: Doc has orders to kill Val, and time is running out for him to figure out a way out of his dilemma.
