Appleseed takes place in the aftermath of World War III, where the General Management Control Office has constructed the experimental city known as Olympus. Built to be a paradise on Earth, Olympus is inhabited by humans, cyborgs, and bioroids (genetically engineered humans designed for increased physical capabilities and decreased emotional capabilities). Bioroids run and control all of the administrative functions of Olympus, ensuring that the city remains the utopian society it was meant to be for all of its citizens. But for some people living in Utopia, the city has become less of a home and more of a cage.
