Set several centuries in the future, a female cyborg named Alita is found in the scrapyard of Iron City by Ido, a compassionate cyber-doctor who takes her to his clinic. When Alita awakens, she has no memory of who she is, nor does she have any recognition of the world she finds herself in. As Alita learns to navigate her new life and the treacherous streets of Iron City, Ido tries to shield her from her mysterious past. However, her street-smart new friend Hugo offers instead to help trigger her memories. But it is only when the deadly and corrupt forces that run the city come after Alita that she discovers a clue to her past - she has unique fighting abilities that those in power will stop at nothing to control. If she can stay out of their grasp, she could be the key to saving her friends, her family and the world she's grown to love.
