Synopsis: The electrifying Emmy Award winning spy drama, "Alias," returns for an emotionally gripping fourth season. Jennifer Garner stars in her Golden Globe Award-winning role as CIA agent Sydney Bristow in this non-stop thrill ride through espionage, adventure and heart-wrenching drama.

After shutting down the malevolent Arvin Sloane and SD-6, Sydney thought she had finally rid the world of evil and avenged the murder of her fiancé. But her life took a shocking turn last year when she mysteriously awoke in Hong Kong to the realization that she had no recollection of the past two years of her life. Everyone had presumed Sydney dead, including her soul mate, CIA agent Michael Vaughn, who had since married agent Lauren Reed. While uncovering the truth about her missing two years, Sydney was stunned to learn that Lauren had been working clandestinely for The Covenant, a crime syndicate bent on the destruction of the CIA. It became Sydney’s mission to convince Vaughn of the facts about his new wife and to eradicate both her and The Covenant. Meanwhile, Sydney’s journey led her and her father, Jack Bristow, to the discovery of Sydney’s half-sister, Nadia Santos, the result of an illicit affair a quarter-century ago between arch nemesis Sloane and Sydney’s mother, Irina Derevko. Finally, unearthing a past misdeed by Jack left Sydney wondering, once again, if she could trust her father.

Even more gripping and emotional events are in store this year for Sydney. She’ll be utterly devastated when she learns who her new boss is at the CIA, but she’ll be thrilled when she finds out the identity of her new partner. She’ll mourn the loss of someone close. She’ll discover the joys and heartbreaks of having -- and being -- a sister. She’ll struggle to define her relationship with the newly-widowed and now soul-tortured Vaughn. And she’ll be sickened to hear the truth about her father’s betrayal -- all the while traveling incognito, outsmarting the bad guys and keeping the world safe. (courtesy ABC Entertainment, 2003)
