Based on the manga from reknown creator Shirow Masamune, in this movie, Deunan and Briareos are both partners and lovers.
As members of ESWAT, the elite forces serving Olympus, they are deployed everywhere trouble strikes.
The two fighters find their partnership tested in a new way by the arrival of Tereus who uncannily resembles Briareos before the wartime injuries that led to his becoming a cyborg.
At the same time, Olympus finds itself under a stealth attack.
Cyborg terrorism, deadly nanotech zealots, and rioting citizens are just some of the threats that Deunan must contend with as she fights to save Olympus.
