[7] Jung_E portrays a desolated Earth in the year 2135 that is no longer habitable due to the rise of the sea level caused by climate change.

Captain Yun Jung-yi is a legendary mercenary of the Allied Forces who led her team to countless successful missions against the Adrian Republic.

Kronoid, an institute in charge of developing AI technologies, convinces her family to agree to clone her brain, promising that they will cover Jung-yi's treatments, her daughter's education and living expenses.

Dr. Yun Seo-hyun is the team leader of research project Jung_E and seeks to memorialize Jung-yi as a hero rather than a failure.

She also learns through the chairman of Kronoid that there is no need to develop combat AI anymore because the Adrian Republic and Allied Forces are entering a treaty.

Kim Hyun-joo and Ryu Kyung-soo also appeared in director Yeon Sang-ho's previous work, 2021 Netflix series Hellbound.
