Talk about packing a lot into a day: Kiefer Sutherland returns for a sixth season as counterterrorism agent Jack Bauer in this popular series in which each episode represents one action-packed hour in our hero's hectic season-long day. This season, terror attacks are striking cities across the U.S. and the government asks Bauer to sacrifice himself to save the country. Mary Lynn Rajskub and D.B. Woodside return to the frenetic series.
