Dr. Andres, an expert in the field of parapsychology, meets Merz, a medium in his mid-40s who claims to be able to make images of his thoughts visible on a television screen. However, Merz needs stimulation from alcohol and women to bring out his abilities. This fact makes scientific research almost impossible. Andres soon succumbs to Merz's fascination. Paranormal images from the past and future also change his relationship with the young photographer, May. When May's intimate secrets appear in Merz's paranormal images, the situation escalates. Andres and May fall completely under Merz's spell. Not even Merz's suicide can free them from it. That same night, Merz's ghostly figure appears on Andres’s television and begins to speak.
