The Emmy Award-winning spy drama, �Alias,� returns to the ABC primetime schedule with a two-hour event, WEDNESDAY, APRIL 19 (8:00-10:01 p.m., ET), on the ABC Television Network.

Editors please note: �Alias� will air in its regular time period beginning Wednesday, April 26 (8:00-9:00 p.m., ET).

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. The electrifying return event includes the birth of Sydney�s baby and reappearance of Michael Vaughn (Michael Vartan).

In the two-hour return event, featuring the episodes �S.O.S.� and �Maternal Instinct,� Jack calls on former Agent Weiss (Greg Grunberg) and the APO team to search for Sydney after receiving a distress call from her. But Jack believes that a larger conspiracy may be in play, thwarting their attempts to rescue her. Meanwhile, Tom�s suspicious actions may suggest he has a hidden agenda, Irina Derevko (Lena Olin) is a surprise partner to Jack and a very pregnant Sydney on a mission to retrieve �The Horizon� � but her allegiances still remain in question -- and Sloane is forced to scramble when Devlin suspects a mole is working inside APO.

Upcoming episodes will reveal the outcome of Sloane�s unholy alliance in his search for the cure for daughter Nadia (Mia Maestro) and the endgame of the Rambaldi prophecy. Other familiar faces from the past will crop up in Sydney�s life � for better or worse -- including best friend Will Tippin (Bradley Cooper) and nemeses Julian Sark (David Anders) and Anna Espinosa (Gina Torres).
