Earlier today, we reported that the highly-anticipated CBS series Supergirl has brought on Jenna Dewan-Tatum to play Lucy Lane, a.k.a. Superwoman. While the cast continues to be filled out, CBS has released a brand new trailer which showcases the mother-daughter relationship between Kara Zor-El (Melissa Benoist) and Alura Zor-El (Laura Benanti). Since Kara left Krypton for Earth at a young age, many wondered how her birth mother would be featured on the show, and this trailer gives us our answer.

Alura is seen appearing before Kara through some sort of vision, which appears to be coming from some sort of mystic object. Aside from the scenes on Krypton, where Kara is sent to Earth, we haven't seen much of Alura, but it seems that she will be giving out advice to her daughter as she continues on her journey to become the hero she was always born to be. We also get a new look at Chyler Leigh as Kara's foster sister Alex Danvers, and Mehcad Brooks as photographer Jimmy Olsen.

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.

The latest additions to the cast include Peter Facinelli, who signed on as Maxwell Lord, and Chris Browning, who stars as the villainous Reactron. The main Supergirl cast is rounded out by Jeremy Jordan as Winn Schott, with Dean Cain and Helen Slater also starring as Kara Zor-El's foster parents, the Danvers. Check out the latest trailer for Supergirl, which debuts Monday, October 26 at 8:30 PM ET on CBS.
