Scanners are men and women born with incredible telepathic and telekinetic powers. This breed of superbrains was developed as an accidental side effect of a tranquilizer administered to some women during pregnancy. Cameron Vale is one such scanner, and he, like most of those with similar powers, exercises the benefits of his special gifts in a safe and judicious manner. But a group of renegade scanners, led by the nefarious Revok, plans to create a race of telepathic ubermenschen who will rule the world. Vale must team up with a like-minded female scanner in order to thwart the plans of the fiendish gang. The protracted end game between Revok and Vale is heightened by a dark secret which is shockingly revealed just before their duel begins.
