The story (no major spoilers)
Kara Zor-El (her comics history) grew up on a fragment of Krypton and watched her world die, unlike her cousin Clark, who was raised in Kansas. She’s older, rougher and far less polished than Superman. When someone harms her dog Krypto, she sets off across the galaxy alongside a young girl, Ruthye, who is on a quest for justice of her own.
