24 - Season 9

Another eventful day in the life of Jack Bauer begins with the heroic agent-turned-fugitive in a race against the clock to save the world while simultaneously staying on the run from the CIA. Set four years after the "24" finale, the series opener finds Jack putting his freedom on the line by coming out of hiding in London to try and prevent a major terrorist attack.

Jack and Chloe struggle to elude the CIA's grasp while searching for a rogue hacker named Derek Yates; Audrey and Mark worry that President Heller could be suffering from dementia.

Kate's hunt for Jack continues as President Heller prepares to address Parliament after a devastating attack. Elsewhere, Margot Al-Harazi demonstrates how much she is willing to sacrifice for revenge.

Terror threat concerns are escalating as the CIA closes in on Jack while he makes his way to the U.S. Embassy; President Heller delivers an impassioned speech to Parliament; Margot asserts her authority; and Kate takes matters into her own hands.

An impending attack brings two unlikely people together to stop it; Margot makes her demands known; and President Heller's order for a military lockdown may be too late.

Tensions between President Heller and Prime Minister Davies boil over, until one of them decides to take matters into his own hands. Meanwhile, Jack has a plan for tracking down Margot, but it involves using someone unexpected—and unsuspecting—as bait; and back at the CIA in London, Jordan raises suspicions about Kate's husband.

President Heller tries to stop Margot from going through with any further attacks, while Jack and Kate race to save the life of a key player in the terror plot, and Jordan is ordered into the field on a perilious mission.

Jack and President Heller put themselves through hell in order to stop Margot Al-Harazi from going through with any more attacks; at the same time, Kate takes drastic measures to find Margot's hideout, while Jordan finds himself in a life-or-death situation.

True colors are revealed in the midst of some very intense circumstances. Meanwhile, Jack and Chloe launch a plan to eliminate the terrorist threat and keep London safe from any more attacks, but to do so first he and Kate need to track down some crucial leads with little time to spare.

Jack remains laser-focused on pursuing his remaining leads; emotions escalate when Kate learns the truth about her husband; and Audrey confronts Mark about the duplicitous things that he has said and done. At the same time, the terror threat widens and the potential devastation becomes all too clear.

Jack leads Kate and Mark on a mission to avert an international crisis, as Audrey tries diplomatic means to avoid full-scale war.

The day comes to an end with Jack doing everything in his power to prevent a terror plot and an international crisis. But to save the world, he's faced with an unthinkable and grave decision.
