Irina (Lena Olin) turns herself in to the CIA, insisting that her main purpose in life is "Defeating Arvin Sloane. SD-6. The Alliance." She also offers to help track down "The Bible," the elusive operations manual for the evil cartel which she formerly headed. But her ex-husband, Jack (Victor Garber), and daughter, Sydney (Jennifer Garner), are extremely skeptical about Irina's sincerity, even after she provides Sydney with the safety measures needed to retrieve a computer disk used by Irina to blackmail other secret agents into complicity -- an assignment given to Sydney by the sinister Arvin Sloane (Ron Rifkin), as yet unaware of Irina's surrender. ~ Hal Erickson, Rovi
