CBS has announced today that its highly-anticipated Supergirl will debut Monday, October 26 from 8:30 PM ET to 9:30 PM ET, following a new episode of The Big Bang Theory. The superhero series will then move into its regular time slot from 8 PM to 9 PM ET on Monday, November 2, after the comedy hit The Big Bang Theory moves from Monday nights at 8 PM back to its normal Thursday 8 PM time slot. The show's official Twitter feed also debuted a brief video, with series star Melissa Benoist revealing the release date, along with another look at her costume, which you can check out below.

Supergirl is an action-adventure drama based on the DC Comics character Kara Zor-El (Melissa Benoist), Superman's (Kal-El) cousin who, after 12 years of keeping her powers a secret on Earth, decides to finally embrace her superhuman abilities and be the hero she was always meant to be. Twelve-year-old Kara escaped the doomed planet Krypton with her parents' help at the same time as the infant Kal-El. Protected and raised on Earth by her foster family, the Danvers, Kara grew up in the shadow of her foster sister, Alex (Chyler Leigh), and learned to conceal the phenomenal powers she shares with her famous cousin in order to keep her identity a secret.

Years later at 24, Kara lives in National City assisting media mogul and fierce taskmaster Cat Grant (Golden Globe Award winner Calista Flockhart), who just hired the Daily Planet's former photographer, James Olsen (Mehcad Brooks), as her new art director. However, Kara's days of keeping her talents a secret are over when Hank Henshaw (David Harewood), head of a super-secret agency where her sister also works, enlists her to help them protect the citizens of National City from sinister threats. Though Kara will need to find a way to manage her newfound empowerment with her very human relationships, her heart soars as she takes to the skies as Supergirl to fight crime. Take a look at the new Supergirl video below with Melissa Benoist, and stay tuned for more on the upcoming series.
