Convinced that Alliance counterintelligence head Ariana Kane (Faye Dunaway) plans to frame him on a murder-extortion rap, Jack (Victor Garber) is forced to rely upon Irina (Lena Olin) to turn the tables on Kane and clear his name. Meanwhile, while on assignment in France to retrieve the prototype for the Triad's missile-guidance system, Sydney (Jennifer Garner) and Vaughn (Michael Vartan) decide to take time out for a romantic rendezvous. Their passion is rudely interrupted by two of Ariana Kane's henchmen, who know that Vaughn is a CIA operative -- and intend to kill him on the spot. ~ Hal Erickson, Rovi
