Raised on a floating remnant of her shattered homeworld, Kara Zor-El (Australian actress Milly Alcock) grew up witnessing tragedy, turning her into a far more jaded, cynical hero than her famous cousin, Superman. When a ruthless space pirate named Krem of the Yellow Hills (Matthias Schoenaerts) brutally attacks her beloved companion Krypto, Kara embarks on an unforgiving interstellar quest across the galaxy to deliver justice. Partnering with a vengeful alien youth named Ruthye Marye Knoll (Eve Ridley), the hardened Kara must traverse dangerous alien planets, battling mercenary bounty hunters like Lobo (Jason Momoa) while confronting her own buried grief.

Australian director Craig Gillespie helms this gritty sci-fi epic, adapting the acclaimed comic book run of the same name by Tom King and Ana Nogueira. The visual spectacle delivers a dark, antiheroic perspective on the iconic DC Comics heroine.
