Burned out veteran Eddie Dugan is just one week away from his pension and a fishing cabin in Connecticut. Narcotics officer Sal Procida has discovered there’s no line he won't cross to provide a better life for his long-suffering wife and seven children. And Clarence "Tango" Butler has been undercover so long his loyalties have started to shift from his fellow police officers to his prison buddy Caz, one of Brooklyn's most infamous drug dealers. When NYPD's Operation Clean Up targets the notoriously drug-ridden BK housing project, all three officers find themselves swept away by the violence and corruption of Brooklyn's gritty 65th Precinct and its most treacherous criminals.
