As the Javits Center construction project ignites a battle for profit in early 1980s Hell's Kitchen, a generational rift threatens the uneasy peace between violent Irish gang the Westies and the Mafia, and draws FBI heat.
Roarke and Sweeney's fallout splits the Westies, pitting old guard against young; Bridget pushes ahead with the mission but faces shattering truths; Polk increases pressure on Sweeney and Gotti; Keenan wrestles with guilt and a son slipping away.
The Westies' fragile deal with the Italians unravels after a reckless kidnapping; Flanagan is released from Bellevue and rejoins Roarke's crew, Keenan is pulled onto an FBI task force, and Bridget receives a dangerous assignment from an IRA contact.
