Worried about her blackout, she consults a most unusual psychiatrist who determines that Megan had been hypnotized.
A neighbor is present when Megan receives a phone call reinforcing a posthypnotic suggestion?which Megan herself is unaware of. It looks as if she has been programmed to do something…but what? Megan, her neighbor, and the psychiatrist decide that the only way to solve the puzzle is to find the hypnotist. And the hunt is on.
