Set in Washington, DC, "Day 7" opens with CTU dismantled and Jack Bauer on trial. His day takes an unexpected turn when former colleague Tony Almeida (Carlos Bernard) returns. Meanwhile, newly elected President Allison Taylor (Cherry Jones) leads the country alongside Chief of Staff Ethan Kanin (Bob Gunton) and First Gentleman Henry Taylor (Colm Feore). A national security crisis prompts an investigation by FBI agents including Janis Gold (Janeane Garofalo), Renee Walker (Annie Wersching), Larry Moss (Jeffrey Nordling) and Sean Hillinger (Rhys Coiro). Although CTU is no longer, Chloe O'Brian (Mary Lynn Rajskub) and Bill Buchanan (James Morrison) are back for another momentous day of shocking events.
