24: Conspiracy

A man and a woman enter a hotel room making out. Everything is passionate until the woman breaks the man's neck. She then takes out all kinds of technical equipment and takes a scan of the man’s hand. The man's ID-card on the floor reveals his identity as Donald Frick of the Department of Defense.

A few hours later, James Sutton, the head of CTU Washington, notifies agent Martin Kail of this development. He does a double take when he sees surveillance footage of the woman.

The suspect appears to be Susan Walker, Martin’s CTU partner and former lover. Martin refuses to be put on the case, but because of a possible link with the kidnapping of James Heller (see Season 4), Sutton wants his best agent. Unexpectedly, Susan calls their office.

Susan warns Sutton and Martin not to come after her. CTU analyst Kelly traces the call and determines the location.

Martin goes to the location Kelly gave him. There, he finds a man whom he subdues. He also finds a router and realizes Susan was never there, but was just routing her calls through the place.

Martin questions the suspect, Christopher Gerber, with force. He refuses to talk, fearing what his employers would do to him. Gerber manages to untie himself, gets his fingers around Martin’s trigger and commits suicide.
