Sydney Bristow (Garner) is a young, athletic, college graduate who was recruited her freshman year as a secret agent for SD-6, a top-secret branch of the CIA. A few years later – after Sydney confides her lifestyle to her boyfriend and the evil head of SD-6, Arvin Sloan (Rifkin), has him killed – Sydney learns that SD-6 is part of a rogue international agency called the Alliance of 12, out to rule the world. She becomes a double agent, working with the real CIA to bring down SD-6 with the assistance of her handler, Michael Vaughn (Vartan), and her estranged father Jack Bristow (Garber) – also a double agent. Along the way, Sydney fights various rival agents, rival terrorist groups, and traitors all the while keeping her cloak-and-dagger lifestyle a secret from her friends.
