Anchored by charismatic lead Melissa Benoist, the female-centric series is a refreshingly human take on the DC comics universe.

What is Supergirl about?

Like her cousin Kal-El, aka Superman, Kara Zor-El is sent to Earth from the planet Krypton. Unfortunately, the 13-year-old’s spacecraft veers off course, and rather than arriving as planned to protect her younger cousin, she finds herself frozen in time in the Phantom Zone.

Finally on Earth but too late for her mission, Kara is taken in by a foster family and represses her superpowers in order to fit in. One day, everything changes and Kara must use her powers in order to save a life.
