Seasons & Episodes
Season 1
Sydney Bristow discovers that her employers at SD‑6 are actually enemies of the CIA, forcing her into a dangerous double life. As she secretly reports to the real CIA, she confronts betrayal—including from her fiancé and possibly even her father—while infiltrating missions that uncover her family’s deep ties to conspiracy.
Season 2
In the second season, plotting against rogue agency SD-6 keeps superspy Sydney Bristow almost as busy as negotiating a relationship with her long-lost mother and dealing with her growing feelings for CIA handler Vaughn. What Syd doesn't know is that there are lots more changes (costume and otherwise) ahead of her... it's going to be a long year!
Season 3
Thrown for a serious loop in the final episode of season 2, CIA agent Sydney Bristow starts season 3 dealing with a life -- and memory -- left in shambles. Luckily she has her resourceful father and her trusty partner to offer assistance as she searches for the truth. But a new double agent may be closer -- and more dangerous -- than Sydney suspects.
Season 4
The action explodes in the phenomenal fourth season when Sydney leaves the CIA to join a powerful new Black Ops unit, having no idea of the reunion in store for her.
Season 5
The final season kicks off with a shocking revelation and never lets you catch your breath as superspy Sydney Bristow faces one mother of a challenge. Old enemies and favorite guests return for the action-packed series finale.
