Marine Sergeant Nicholas Brody return home eight year after going missing in Iraq. Carrie Mathison, a driven CIA officer, suspects he might be plotting an attack on America.
Carrie Mathison, a CIA operation officer, is on probation after carrying out an unauthorized operation in Iraq. As a result, she has been reassigned to the Counter terrorism center. Whilst in Iraq, she was warned that an American prisoner had been turned by Al-Qaeda. When Nicholas Brody, a U.S. Marine Sergeant, is rescued after being held hostage since 2003, she suspects that he is the turned American prisoner. Brody is received home as a war hero, so Carrie goes to any lengths possible, ignoring protocol, to catch him out.
