Four explosive hours after being unwillingly drawn back into action, Jack Bauer re teams with a risky Renee Walker to track some very dangerous leads. Meanwhile, back at CTU, a desperate Dana Walsh faces tense and untimely circumstances when her ex-con boyfriend from her home in Texas shows up and threatens to reveal her past life to her employers unless she does some things for him. Elsewhere, emotions escalate when President Taylor learns of a larger looming threat that jeopardizes the peace accord with President Hassan. Also, Sergi Bazhaev, the Russian arms dealer, agrees to let his son, Josef, try to get medical treatment for his other son whom has radiation poisoning. Written by FOX Publicity
Lots of action as the undercover efforts blossom. Renee is willing to die for this. Jack tries to rein her in, but nothing is working. Still, with improvisation, things continue on course. Those Russians are really awful characters. Dana's boyfriend is making promises that we know he won't keep. She is in mighty deep stuff right now and has committed a felony. Her erratic behavior is being noticed.
