The world, devastated by a long global conflict, is ruled from the vast city of Olympus by the General Administration Agency. This Agency is run by human-hybrid clones known as Bioroid, made from the genes of the best and brightest.
Former Los Angeles S.W.A.T. officer Deunan Knute and her cyborg partner Briareos, both become residents of Olympus after being scouted by ES.W.A.T., a special counter-terrorist division of the Global Police.
One such terrorist group which they fight is the Human Liberation Front, which attacked Olympus in the midst of the launch of the Ark Program, a plan to entrust the future of humanity to Bioroids.
However, subsequent investigations will reveal that someone else had been manipulating the Front from behind the scenes.
Deunan, Briareos, and the rest of the Olympus's ES.W.A.T force fend off an Argonaut attack.
Deunan and Briareos are sent to end a hostage situation on a plane with 3000 passengers. But when they arrive the entire plane is eerily empty.
A surge in bioroid suicides has caused a stir throughout Olympus. Deunan steps in to investigate this mysterious situation.
A Kottos robot on the police force malfunctions in an unexpected way after meeting a little girl.
While on a security assignment, members of ES.W.A.T. are infected by something that cause madness and tremendous bloodthirst. Not even Deunan is immune to its effects.
Deunan embarks on a solo mission to infiltrate the Argonauts and learn more about an enormous and extremely high-tech Landmate.
As the Stymphalean Landmate approaches Olympus with a nuclear warhead, Briareos and ES.W.A.T. rush to diffuse the situation.
Deunan is assigned to provide security to a Poseidon ambassador of goodwill aboard a submarine. But things go awry when the submarine malfunctions and other passengers begin to die mysteriously.
A goodwill ambassador arrives from Poseidon... except she looks and sounds exactly like Deia, who should be dead.
Deunan and Briareos are assigned to protect a bioroid sculptor from Deia, who is bent on killing a specific group of them.
ES.W.A.T. is dispatched to the Argonaut to provide security for the final bioroid on Deia's hit list. Little does anyone know Deia has already made the first move.
Deunan and Briareos face off with Deia in a final battle.

Some time after the Deia incident, ES.W.A.T. is called in to supervise a diagnostic check of the Gaia Computer's systems. Soon after, unmanned Landmates and Auto Insectors start to malfunction.
