Angel is a tough, beautiful cop in the Special Security Force, assigned to protect a future version of Tokyo against terrorists, especially Communist terrorists. When she and her partner Raiden are assigned to take out the Red May organization, mysterious beings appear who quickly reduce the would-be provocateurs to so many burned and mutilated bodies. The assignment grows even more complicated when Raiden disappears after he's badly injured in a motorcycle accident. While the Special Security agents are fighting the commies, a cadre of corrupt politicians schemes to have them all murdered before they uncover who's really behind the actions of the Red May and other radicals. Cyborgs, nuclear-waste dumping, psychic mutants, superweapons, and economic terrorism figure heavily in this violent adventure.
