Author, John Morlar (Burton) has a peculiar gift. He can induce calamity and disaster at will. Perhaps that's why someone bludgeoned him to within inches of death. By all accounts he should have died but he's kept alive on machines in a hospital where his brain scans are remarkably active. Inspector Brunel (Lino Ventura) leaves no stone unturned in his search for Morlar's assailant. His search eventually leads him to Dr. Zonfeld (Remick) who gives him accounts of their sessions to try and help Brunel find leads. It's through her that we learn, in flashback, of Morlar's gruesome past.
