Watch Supergirl

The series is based on the DC comics franchise and tells the story of Superman's cousin, Kara Zor-El aka Supergirl. The show was created by Ali Alder and is connected to other shows, The Flash and Arrow. All of these series take place within the same universe, leading up to a crossover between the three superheroes.

The story focuses on a twenty four year old version of the heroine finally coming out of hiding and using her powers to prevent a disaster from devastating the Earth. The origin story in this adaptation is a different retelling of the character's upbringing. In the comic Supergirl is a teenager; in this version she was taken taken in at the age of 13 by the Danvers family and is forced to hide her powers until later in life.

Many other superheroes from the DC universe will make smaller recurring appearances throughout the show. They will serve as potential allies or archenemies. However the star of the show is still Supergirl. The main supervillain is Ben Krull aka Reactor, an enemy of Superman who seeks revenge by killing Supergirl.

The series will be broadcast on CBS and is produced by both conglomerate companies; DC entertainment and Warner Bros. Television. Despite being produced by the same parent companies, the show did not make it to the same network as Arrow and The Flash, which is The CW. Cross overs between the series and networks are planned.
