Premiering in September 2001, Alias has built a steady and loyal following among television viewers. The show combines the fast pace action sequences of 24 with the conspiracy theory backdrop of the X-Files. It also doesn't hurt that the show centers itself around a character that's a beautiful and mysterious woman. But the true strength of Alias, as with most successful TV shows, is its unique and creative writers who manage to always keep their audience on edge

Jennifer Garner (star of 13 Going On Thirty) plays the role of Sydney Anne Bristow, a beautiful, intelligent American woman recruited to work for the government's super secret SD-6 agency. However, problems arise when her fianc is murdered by the agency she works for, and she ultimately discovers that SD-6 is not a legitimate government organization at all In seek of revenge, Sydney contacts the CIA, and they deploy her as a double agent. Meanwhile, Sydney's estranged father, Jack (Victor Garber), also works as a double agent, and their relationship blossoms as a result of their work. Together, they manage to eliminate SD-6, and now both work full-time for the CIA where they're accompanied by fellow colleagues Marshall Flinkman (Kevin Weisman), Marcus Dixon (Carl Lumbly), and Michael Vaughn (Michael Vartan)

The Alias (Season 4) DVD features a number of exciting episodes including the season premiere "Authorized Personnel Only" in which Sydney quits the CIA in favor of joining a secret organization known as Authorized Personnel Only. Meanwhile, the answers Sydney uncovered in Wittenberg threaten to ruin her relationship with Jack, at least until she is forced to join forces with her father in an effort to track down a dangerous samurai Other notable episodes from Season 4 include "Dtente" in which Sydney and Nadia go undercover together in order to dig up the location of a deadly chemical, and "Nightingale" in which Sydney and Vaughn risk their lives to find out the truth about Vaughn's father
