In the sixth season (2007), 20 months have passed since Day 5. After being captured by the Chinese for his involvement in the events of Day 4, Jack Bauer is returned to the United States Government a broken, yet honorable, man. To stop a series of devastating attacks on the US, CTU has agreed to hand Jack over to a terrorist mastermind, Abu Fayed, who is bent on revenge. Jack survives and, after a nuclear attack on American soil, vows to retrieve the remainder of the nuclear weapons used in the day's attacks. The White House, meanwhile, suffers from an internal power struggle between President Wayne Palmer and his Vice President Noah Daniels, forcing Palmer's staff to choose sides, which in turn affect CTU and its employees. After eliminating the day's threats, Jack is forced into a personal crusade to save Audrey Raines from those he fears most, and discovers that his family is more involved with the Chinese than he ever imagined...
