After a man with extraordinary, and frighteningly destructive, telepathic abilities is nabbed by agents from a mysterious rogue corporation, he discovers he is far from the only possessor of such strange powers. Some of the other “scanners” have their minds set on world domination, while others are trying to stop them.

A breed of humans with dangerously powerful telepathic abilities -- the scanners -- are being recruited by a corrupt police commander, John Forrester, in his crusade to take over the city.
