Synopsis by Josh Ralske
Jack (Kiefer Sutherland) is battling heroin addiction after going undercover to bust Ramon Salazar (Joaquim de Almeida). Chase (James Badge Dale) is the only one who knows that Jack is going through withdrawal as CTU addresses the biological terror threat. Wayne (D.B. Woodside) tells Tony (Carlos Bernard) that the president will not give in to the terrorist demand to free Ramon, but promises that CTU will have all the resources they need. Wayne tells David (Dennis Haysbert) that he might be able to get a copy of their opponent's playbook for that night's debate. David rejects the offer, but Wayne does it anyway, and later tells David that the opposition intends to use some new information about Anne (Wendy Crewson) against him. Kim (Elisha Cuthbert), going against Chase's wishes, decides to tell Jack about their relationship. Jack later expresses his displeasure to Chase. Jack explains that the job has ruined every relationship he's ever had. Later, Jack sends the resentful Chase back to CTU to conduct a routine interrogation, in order to keep him out of harm's way. CTU discovers that the virus might be in powder form, which leads them to pursue Kyle Singer (Riley Smith), who has just returned to Los Angeles from Mexico with what he thinks is a bag of heroin. And, in a surprise twist, Hector Salazar (Vincent Laresca), running the operation from Mexico, and his brother have an inside link to CTU.
