Now, under constant surveillance from Gaines, Jack goes back to CTU where Nina inadvertently gets in the way of Gains' plan. Teri tries to escape from York, but her call to CTU only brings more help for York. Meanwhile, Palmer tries to convince his family that they need to tell the press about a secret personal tragedy from their past before it's too late.

A man named Andre Drazen contacts Gaines. Clearly disappointed that the morning's events did not go as planned he threatens to relieve Gaines of his assignment. Across town, Jack kidnaps Cofell and, after hearing Cofell's Serbian accent, has Nina break into an old case file profiling a secret mission Jack was on in Belgrade and Kosovo two years ago. Then Jack meets Cofell's contact: the man who claimed to be Alan York.

While Green pressures Nina and Tony to reveal Jack's whereabouts, York leads Jack to Gaines' compound where Jack attempts to rescue Teri and Kim without backup from CTU. Meanwhile, Senator Palmer's plan to prevent a murder fails and he begins to suspect his wife may have a hand in the conspiracy.

Jack confronts Gaines who, realizing he has failed Drazen's assignment, chooses death over helping Jack. Back at CTU, Nina and Tony interrogate the mother of the traitor and learn of a secret bank account containing deposits from Belgrade. They also learn that additional assassins may be making their way to Los Angeles.

While Jack is questioned at the CTU, Teri and Kim are taken to the clinic to be examined. Meanwhile, certain he recognizes the name Jack Bauer, Palmer has Jack's background investigated. When he discovers that Jack was the sole survivor of a secret mission that he authorized two years ago, Palmer becomes convinced Jack is out for revenge and insists on talking to Jack face to face.
