In a post-apocalyptic future, a police raid devastates the imposing headquarters of a religious cult. After assessing the casualties, two officers find a winged girl lying unconscious in chains and attempt to resuscitate her. However, she barely awakens before a group of specialists in protective suits hastily takes her away. Disappointed to see the angel-like being confined once again, the policemen resolve to set her free and begin making the necessary preparations. Despite the need to infiltrate a restricted research facility, nothing stops the duo from readily throwing themselves into a deadly rescue mission.
