Homeland

Reeling after losing key players in Nazir's plot against America, the CIA orders polygraphs on everyone who came in contact with them, including Brody, which Carrie sees as an opportunity to finally learn the truth.

The relationship between Carrie and Brody becomes more complicated when they head into the countryside for the weekend, while Mike and Jessica face the fallout of the truth about their relationship, and Saul catches Aileen on the run to Mexico.

As Carrie and Saul reel from the news that Walker is alive, the intelligence community clashes on the best way to capture him; Brody learns a shocking truth about his captivity.

After his attempt to sever ties with Abu Nazir, Brody finds himself reliving his captivity and recommits to his mission; Carrie finds herself in the middle of a public relations nightmare on the heels of the mosque shooting.

Carrie and Saul identify Walker's contact in Washington but their target has diplomatic immunity; Brody is approached to run for a disgraced congressman's seat in the House of Representatives.

In the wake of the explosion, Saul finds Carrie hospitalized and manic, but realizes her chaotic theories have merit; before his congressional campaign begins, Brody takes his family on a weekend trip to Gettysburg, where he retrieves an important item.

While Carrie is near catatonic and confined to bed, Saul investigates the unsettling implications of her timeline; Walker secures a perch for his mission; Brody makes his final preparations for the Vice President's policy summit at the State Department.
