With a new day comes a new leader for the sixth season, as Wayne Palmer (DB Woodside), brother of former president David Palmer, has taken the reins from the corrupt Charles Logan (Gregory Itzin). But President Palmer has little time to celebrate his election, as America faces yet another grave threat, this one from Islamic terrorist Abu Fayed (Adoni Maropis). By way of introduction, Fayed orders suicide bombings of 10 U.S. cities over a period of 11 weeks. But he's just getting warmed up-before Day 6 comes to a close, the threat goes nuclear. Trying to prevent further bloodshed, as always, is Jack Bauer (Kiefer Sutherland). Out of the frying pan and into the fire, Jack is freed after months of torture in a Chinese prison, only to be handed over to Fayed in exchange for seemingly valuable intel. Tackling the day's dangers on the CTU front are new personnel additions Mike Doyle (Rick Schroder), who replaces the fallen Curtis Manning as director of field operations, and Agent Milo Pressman (Eric Balfour), who has a history of butting heads with his new boss. Day 6 also provides the first glimpse of Jack's blood relatives, his father Phillip (James Cromwell) and brother Graem (Paul McCrane). But it's far from a touching family reunion, as one of Jack's toughest challenges is determining where the other Bauers' loyalties lie. Several new faces make their way to 1600 Pennsylvania Ave., including steely vice president Noah Daniels (Powers Boothe) and presidential advisers Reed Pollock (Chad Lowe) and Thomas Lennox (Peter MacNicol), each of whom has his own agenda. Making a surprise return later in the day are former president Logan, his ex-wife Martha (Jean Smart), and former Secret Service agent Aaron Pierce (Glenn Morshower), all of whom play brief but pivotal roles in the season's developments.

In the midst of Jack Bauer's (Kiefer Sutherland) testimony before a Senate subcommittee, a new terror plot aimed at Washington, D.C. sends the former CTU agent and Renee Walker (Annie Wersching) on a desperate race against time. Meanwhile, an old ally may now be their most dangerous enemy in this release featuring all 24 episodes of 24: Season Seven.
