In Chicago, Jimmy bonds with one of Johnny Torrio's prostitutes, Pearl, and finds himself increasingly at odds with the hot-headed Al Capone. Back in Atlantic City, Nucky looks to leverage his relationships with ambitious U.S. Senator Walter Edge, as well as Jersey City Mayor Frank Hague. Eli and Chalky go to extremes to interrogate a KKK member; Lucky Luciano sets his sights on Jimmy's "wife"; Margaret impresses at Nucky's lavish birthday party, while Lucy tries to protect her territory.
