In a post-COVID world a hundred years in the future, wars and drought have created food scarcity, and a tyrannical world government has taken over. Teenager Kim has been imprisoned with her family in a labour camp for ten years, but she manages to escape to a safehouse on the outskirts of the city. There, an elderly woman introduces her to a community of dissidents who have become self-sufficient while hiding in the mountains. Kim becomes active in the resistance, learning to fight the dangerous government-created humanoid robots used to control the citizens. When she learns that her sister Christina has been forced into a detention centre where people are brainwashed, she must hatch a daring plan to break in and save her before it's too late.
