All three instalments of the anime series written by Noboru Aikawa and set in Tokyo 2027. In Part 1 the inhabitants of Mega-Tokyo are being killed by renegade Voomers, the cyborgs they created to do their unwanted jobs. When the Advanced Police are brought in, one of them, Leon, realises a beautiful female Voomer has a special grudge against him. In Part 2 the Paradise Loop subway is stalked by a vicious murderer and the Advanced Police are on the trail of a Voomer-killer who is murdering subway tramps and prostitutes. Whilst in Part 3 the Government enlist in a new project that could do away with the AD Police. Using the remains of a critically wounded officer Billy Farnwood, they create an experimental Anti-Voomer Cyborg. However, once transformed, Billy feels trapped in an unfeeling metal shell and unable to cope with the feelings of pain and anger. The scene is set for a running battle through the corridors of AD Police headquarters.
