Following the deadly Langley bombing that is blamed on disgraced congressman Nicholas Brody (Damian Lewis) and having helped him escape the U.S., Carrie Mathison (Claire Danes) is desperate to solve the case and clear Brody's name as the third season of the conspiracy thriller begins. But Carrie's efforts are threatened when she becomes the focus of a hostile Senate investigation led by Sen. Andrew Lockhart (Tracy Letts) who believes the CIA is covering up the truth about the attack. Saul Berenson (Mandy Patinkin), now CIA chief, also feels the heat of the probe and it begins to undermine his efforts to revive the Agency. Trouble also brews in the Brody household when Dana (Morgan Saylor) starts exhibiting destructive behavior and runs away from home. As for Brody, who has a $10 million bounty on his head, he begins to recuperate from a gunshot wound in Venezuela where he is held captive by armed gunmen in a ramshackle Caracas building called the Tower of David. With no passport, no money and no chance of escape, Brody slowly begins to realize that he may have to live out the rest of his days in this slum dwelling where Carrie has arranged for him to at least be safe.

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.
