Season 4 of the Prohibition-era drama opens in February 1924 as Nucky (Steve Buscemi) makes peace with New Yorkers Masseria (Ivo Nandi) and Rothstein (Michael Stuhlbarg), moves into the abandoned Albatross Hotel and, coincidentally, spreads his wings with a potential real-estate bonanza in Florida, where he's smitten with a saucy barkeep (Patricia Arquette). Back in Atlantic City, Chalky (Michael K. Williams) runs the boardwalk's Onyx Club, though the mysterious Harlem intellectual Dr. Narcisse (Jeffrey Wright) challenges his North Side reign, and Eddie (Anthony Laciura) finally gets a promotion. In Philadelphia, Eli's son Willie (Ben Rosenfield) dives in over his head at college; while in the Midwest, Nelson (Michael Shannon) pulls double duty for Chicago mobsters Capone (Stephen Graham) and O'Banion (Arron Shiver), and a wandering Richard (Jack Huston) reconnects with his roots. With Shea Whigham, Brian Geraghty, Ron Livingston, Margot Bingham, Anatol Yusef and Domenick Lombardozzi.

Season 3 of the black comedy about cutthroat management consultants begins with Marty (Don Cheadle) starting his own firm, Kaan and Associates. He desperately misses Jeannie (Kristen Bell), but he continues to keep his feelings to himself. The two do work together, however, on a plot to pit rival grocery clients against one another, so the two wheeler-dealers can reap a huge profit. Of course, things don't go quite as planned. Meanwhile, changes at Galweather and Stearn, including the return of the ruthless Rainmaker (Griffin Dunne), cause trouble for Jeannie and set her on a path of destruction at the firm. And things aren't any better for Clyde (Ben Schwartz). His life is made miserable when he works under Monica (Dawn Olivieri) and it becomes even more brutal when he is forced to work from her home. As for newly married Doug (Josh Lawson), Sarah (Jenny Slate) tells him she wants them to have a baby and that she has already stopped taking birth-control pills.
