Picking up where Scanners left off, this sequel has good and evil scanners combatting when a crooked politician schemes to gain control of a major city. Scanners are people who, because their mothers had taken a certain drug during pregnancy, have acquired telepathic powers. Here, a "bad-guy" scanner escapes from a mental center and is hired by the politician to use his powers to gain control of others' minds, and then, their actions. A "good-guy" scanner teams with his sister to thwart these plans.
