Homeland

When CIA agent Carrie Mathison's unorthodox investigation of threats to US security in Iraq leads to a serious diplomatic incident, she is stripped of her field status and assigned to a desk job.

Although her investigation has been cut short, she hears from her Iraqi source that an American prisoner of war has been 'turned'.

Carrie becomes convinced that this information relates to the return of Sgt Nicholas Brody, missing in action (and presumed dead) for eight years.

After receiving intelligence on an al-Qaeda safe house in Afghanistan, Navy SEALS stormed the premises, killed 13 terrorists, and found Brody in a cell.

The CIA treats the rescue as a hero's return from war, but the timing is too suspicious for Carrie to ignore.

Already on thin ice, she breaks protocol to prove her theory that Brody was turned during his many years in captivity, is working for al-Qaeda, and now poses a major threat to his own country.

Brody receives a hero's welcome at home, but it's clear that the years of torture and abuse at the hands of al-Qaeda have taken their toll.

Physically scarred and emotionally plagued by harrowing flashbacks of his long incarceration, he struggles to reconnect with his wife and teenage children, who feel that a stranger has returned to them.
