After World War 3 the General Management Control Office constructs an experimental city known as Olympus. It is inhabited by humans, cyborgs, and bioroids. Bioroids are a genetically engineered beings created to serve Mankind. They oversee all the administration duties of Olympus. Olympus was meant to be a utopian society, but for some, it feels more like a cage. Calon Mautholos, an Olympus city police officer, is one of the many who feel that way.
Calon secretly conspires with a terrorist, A. J. Sebastian, to destroy Gaia, a super computer that runs the various utilities and networks of Olympus. Out to stop them are Olympus City ESWAT (Enhanced SWAT) team members Deunan Knute and Briareos Hecatonchires. Deunan and Briareos are determined to stop the terrorist plot by any means necessary.
