Boardwalk Empire - Season 3 Episode 12

A gang war erupts in Atlantic City, with Gyp and nine men of his own and 40 of Joe Masseria's against Nucky, Eli, Capone's Chicago crew, and Chalky's men. Gyp's holed up at Gillian's; Nucky at a lumber yard. It's a war of attrition, with Nucky having to keep Capone and Chalky's men from killing each other while he negotiates with Rothstein by phone. Rothstein runs his own game with Luciano, Lansky, and heroin, Margaret calls on an older couple, and Richard is out there somewhere focused on protecting Tommy.
