Professor Phillip Goodman, psychologist and arch-skeptic, has his rationality tested to the limit when he stumbles across a long-lost file containing details of three terrifying hauntings. Shaken by what he reads, Goodman embarks on a mission to find rational explanations for these ghostly stories. As Goodman investigates, he meets three tormented people, each with a tale more frightening, uncanny and inexplicable than the last. Night watchman Tony Matthews had a horrifying encounter in an empty warehouse and it has haunted him for years. Teenager Simon Rifkind took a late-night drive that has rendered him unable to sleep. Mike Priddle, a brash banker, has had his worldview shaken to the core by unquiet spirits that apparently inhabit his otherwise perfect existence. As Goodman digs into their stories, his carefully maintained and rational world starts to dissolve around him.
