Nucky (Steve Buscemi) is awash in memories from pier-boy days growing up in 1884 Atlantic City, when the young Nucky (Nolan Lyons) caught the eye of the Commodore (John Elllison Conlee). In 1931 Cuba, Nucky joins Sally Wheet (Patricia Arquette) and, with a U.S. Senator in tow, forges ties with Bacardi Rum in hopes of Prohibition's repeal in the U.S. Working on Wall Street, Margaret (Kelly Macdonald) finds herself in the hot seat when her boss, facing an internal investigation, decides his own future. Down but never out, Chalky (Michael Kenneth Williams) seizes an opportunity to extricate himself from a difficult situation. In New York, Lucky Luciano (Vincent Piazza) sets in motion a bold plan that reverberates all the way to Nucky in Cuba.
