"Alias" centers around a young lady named Sydney Bristow. She is a spy for a CIA off-shoot code-named "SD-6." When she finds out that SD-6 is not, in fact, CIA, she decides to become a double agent in order to bring down this terrorist organization. She joins with her father, Jack, who is also a double agent with the CIA, but with whom she has little to no relationship. This lack of relationship provides a basis for future stories, and provides drama outside what is specific to this TV show.

Each episode is self-sustaining, so the audience is never completely lost, but keeps the story going, so each episode builds on the last. In each episode, Sydney works with a group of people to save the world and provide protection that most people don't even know they need. Sydney, in almost every episode, is required to disguise herself in order to complete a mission, or get information for the central story. These aliases are what give the show its name, and provide something unique and original for television audiences.

Because Sydney is a spy, she has various talents, including martial arts, so each episode uses these to provide action and drama. Each episode centers around one mission, but the drama is not just specific to these missions. Parallel missions, to provide insight into the central story, are also important, and provide plenty of drama for the audience. Sydney is extremely capable, and never gives up, despite multiple chances to quit the spy trade, and live a normal life.

Alias is a series that is currently running and has 5 seasons (106 episodes). The series first aired on September 30, 2001.
