Complete story — includes the ending
It's a full-scale war in Atlantic City and bodies are piling up on both sides. Based in a lumber yard, Nucky seeks to weaken the Rosetti–Masseria alliance while struggling to keep peace between Capone and Chalky. In New York, Luciano is framed by Masseria and Rothstein with the aid of fake police. Gillian makes a failed attempt to woo, drug and presumably kill Rosetti. Nucky strikes a deal with Rothstein to break Rosetti's power. Chalky and Capone's army massacre Masseria's men as they are retreating to NYC. Richard storms Gillian's house and kills many of Rosetti's men but Rosetti escapes. Nucky uses his political connections to settle a score with Rothstein. Richard gives Tommy a new home at Julia's, sacrificing his relationship with her in the process. Rosetti meets with his three remaining henchmen but on orders from Nucky, Gyp's main assistant stabs him to death while he is urinating on a beach. Nucky tracks down Margaret, who ends their relationship. A depressed Nucky walks the boardwalk where he is recognized by other pedestrians. While he is lonely, he has regained control of Atlantic City.
