The year is 2563, 300 years since “The Fall.” The only sky city left is Zalem, where the residents of Iron City, which resides directly below, can only hope to ascend to one day. While scavenging a junkyard, Dr. Dyson Ido (Christoph Waltz) discovers the upper half of a young female cyborg with a fully functional brain. He puts her back together and names her Alita (Rosa Salazar), after his late daughter. Alita has no memory of her past life, but quickly learns to navigate the dangerous streets of Iron City and discovers she is quite the skilled fighter. She will need those talents as dark forces are beginning to line up against her.
