Description: Earth has been devastated by drastic climate change, and humankind migrates to new shelters in outer space. The civil war that occurs there continues on for decades, and Yun Jung-yi (Kim Hyun-joo) becomes a legendary mercenary and military strategist with countless victories to her name. But one failed mission puts her in a vegetative state. Kronoid, a military A.I. development company, attempts to create the ultimate combat warrior by cloning her brain. 35 years later, Jung-yi's daughter Yun Seo-hyun (Kang Soo-youn) participates in this effort as the head researcher of the JUNG_E project. When little progress is made despite numerous cloning and simulation attempts, Kronoid abandons the research to launch another project. Seo-hyun learns of their plans and resolves to save JUNG_E.
