Margaret Matheson (Sigourney Weaver Sigourney Weaver), PhD in psychology, is good at analyzing all kinds of unexplained supernatural phenomena by scientific means, and is even more skeptical about the so-called superpowers. With the help of assistant Tom Buckley (Hillian Murphy Cillian Murphy), they go deep into the countryside and expose one "psychic" scam after another. At the same time, the superpower Simon Silver (Robert de Niro Robert De Niro), who caused a sensation in the 1960s and 1970s, made a strong comeback, causing a new wave of craze. Marguerite had let Simon's disciples reveal their true colors, but she always avoided the confrontation with Simon. The push of some people seemed to make their duel possible, but Margaret died suddenly. With grief and indignation, Tom decided to challenge Simon alone. He didn't know what he was going to face.
