The Counteragent


Episode Info

Infected with the virus unleashed by Irina's successor Sark (David Anders), Vaughn (Michael Vartan) has but a few days to live. In order to find an antidote for the virus, Sydney (Jennifer Garner) is forced to place her trust in the highly unreliable Irina (Lena Olin). Ultimately, Syd finds herself at the deserted Paldinski nuclear-sub training base in Estonia, where she is confronted by Sark. With surprising expansiveness, Sark offers to spare Sydney and give her the antidote -- but only if Sloane (Ron Rifkin) is delivered into the hands of assassins.
