In the conclusion of a two-part story, Sydney (Jennifer Garner) and her father, Jack (Victor Garber), team up to rescue the SD-6 agents held hostage at the Credit Dauphine headquarters by vengeance-seeking former agent McKenas Cole (Quentin Tarantino) -- a mission that will require them to save the life of the hated Arvin Sloane (Ron Rifkin). Syd and Jack are aided by Vaughn (Michael Vartan), who defies CIA orders not to take a hand in the rescue efforts. Meanwhile, Will (Bradley Cooper) is on the verge of putting all the pieces together in the mystery of David's murder. ~ Hal Erickson, Rovi
