Two investigators of paranormal hoaxes, the veteran Dr. Margaret Matheson and her young helper, Tom Buckley, study the most varied metaphysical phenomena with the aim of demonstrating their fraudulent roots. Simon Silver, also a mythical psychic, reappears to turn into the struggle to both orthodox professional and science sceptics. Tom starts to build up a rigorous obsession with Gold, whose magnetism gets stronger with each new symptom of events that are inexplicable. As Tom gets closer to Silver, anxiety mounts, and his world view is threatened to its core.
