As season three of the ABC espionage series gets under way, secret agent Sydney Bristow (Jennifer Garner) has still not entirely adjusted to the startling revelation that she has somehow lost track of two years in her life -- and that her partner and erstwhile lover Michael Vaughn (Michael Vartan) is now married to Lauren Reed (Melissa George). Also, she is informed that her double-agent father, Jack (Victor Garber), who thought Sydney was dead, has been jailed -- in solitary confinement -- for a year, and her duplicitous boss, Sloane (Ron Rifkin), has disavowed his evil ways and gone straight. But just as in previous seasons, what seems true on the surface is a different story as Sydney digs deeper into the mystery of her missing years. Placed back on active duty, Sydney tortuously tries to put the pieces back together, with Vaughn at her side and Lauren agonizing over the likelihood that her marriage is doomed. Various links to Sydneys past include her old nemesis Julian Sark (David Anders), who has hatched a scheme to cripple the nations satellite system; and freelance thief Simon Walker (Justin Theroux), whose team is involved in stealing a dirty weapon. There are also unexpected encounters with Sydneys old friend Will Tippin (Bradley Cooper), newly dragged from the bowels of the Witness Protection Program, and the redoubtable Allison Doren (Merrin Dungey), the evil doppelganger of Sydneys murdered roommate, Francie. Throughout, there is a concerted effort to prevent Sydneys memory from coming back -- an effort engineered not only by her enemies, but by those who know that she is harboring a terrible secret that will destroy her once she knows all. In the mid-season episode Full Disclosure, Sydney finally receives the whole shocking story about those lost two years, and her complicity in the murder of a Russian diplomat. Thereafter, were back to the basics, with Sydney and Vaughn collaborating on a variety of top-secret missions, several tied in with the ubiquitous Rambaldi code, which when broken will lead to a super-weapon capable of wiping out all of humankind. And in the time remaining in season three, the scorned Lauren is at the center of a startling betrayal -- and, ultimately, Sydney is slapped with a bitter disillusionment that makes all past disillusionments in her life pale in comparison. ~ Hal Erickson, All Movie Guide
