Two daring test subjects, Adán and Orión, seek to prove the existence of God by submitting themselves to a scientific experiment conducted by a mysterious religious organization.

Two investigators of paranormal hoaxes, the veteran Dr. Margaret Matheson and her young assistant, Tom Buckley, study the most varied metaphysical phenomena with the aim of proving their fraudulent origins. Simon Silver, a legendary blind psychic, reappears after an enigmatic absence of 30 years to become the greatest international challenge to both orthodox science and professional sceptics. Tom starts to develop an intense obsession with Silver, whose magnetism becomes stronger with each new manifestation of inexplicable events. As Tom gets closer to Silver, tension mounts, and his worldview is threatened to its core.

A series of brutal crimes are happening in the city. The private detective Roberto Parra believes that the crimes are related to her sister, murdered months ago.
