Professor Phillip Goodman, a psychologist and arch-skeptic, has his rationality tested 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. During his investigation, 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 that has haunted him for years. Teenager Simon Rifkind took a late night drive that has rendered him unable to sleep. And banker Mike Priddle has had his worldview shaken to the core by unquiet spirits that apparently inhabit his otherwise perfect existence.
