Warner Bros. have released the first trailer for Supergirl season 4.
Season 3 saw Supergirl stop Reign and the other Worldkillers’ threat to humanity and our planet, and in the process Kara was shocked to find her mother Alura alive and living in a salvaged Argo City that survived the destruction of Krypton. Reconnecting with her past caused Kara to realize that her true home is now here on Earth, where big changes are taking place for her and all of her friends in National City and also, it appears, for a doppelganger in Russia! Season 4 promises to be full of surprises, action, adventure, and lots of big revelations for Supergirl, Alex, James, J’onn, Lena, and Brainy. From Berlanti Productions in association with Warner Bros. Television, Supergirl’s fourth season will premiere in its new Sunday 8/7c time slot on The CW this fall.
