Supergirl Season 1 Episodes

20 Episodes 2015 - 2016

For the 12 years since crash-landing on Earth after the destruction of her home planet Krypton, Kara Zor-El (Melissa Benoist) has kept her superhuman powers a secret. Cousin to Superman, Kara grew up in a foster family and learned that in order to protect them, and herself, she needed to fit in. In season 1 of this superhero action-adventure drama, an unexpected disaster forces Kara to reveal her powers, inadvertently making her National City's new hero: Supergirl. Hank Henshaw (David Harewood), the head of a top-secret government organization and the boss of her foster sister, Alex (Chyler Leigh), enlists Kara to help them protect the city from a group of alien criminals released after the destruction of Krypton. Kara must learn to balance her human life, where she works for one of the top media executives Cat Grant (Calista Flockhart), and her life as Supergirl.
