Set in Washington, D.C., Day Seven opens with CTU dismantled and Jack Bauer (Kiefer Sutherland) on trial. Bauer's day takes an unexpected turn when former colleague Tony Meida (Carlos Bernard) returns after being presumed dead. Meanwhile, President Allison Taylor (Cherry Jones) leads the country alongside White House Chief of Staff Ethan Kanin (Bob Gunton) and First Gentleman Henry Taylor (Colm Feore). An unthinkable national security crisis prompts an investigation by a team of FBI agents including Agent Janis Gold (Janeane Garofalo), Agent Renee Walker (Annie Wersching), Agent Larry Moss (Jeffrey Nordling), Agent Sean Hillinger (Rhys Coiro) and security specialist Michael Latham (John Billingsley). Although CTU no longer exists, Chloe O'Brian (Mary Lynn Rajskub) and BIll Buchanan (James Morrison) are back for another momentous day of shocking events.
