'In the film, based on Robert Heinlein's novella, the title character is struck one evening with the realization that he has no memory of what he does during the day. Distraught over his predicament, and particularly concerned that he might be engaged in some nefarious activities, he contacts a husband and wife detective agency and asks them to surreptitiously follow him. The truth takes a dark and ultimately earth-shattering turn as their investigation leads to a series of frightening revelations, beginning with a group of shadowy figures who gravely warn of dire consequences unless the pair immediately cease their inquiry into the nature of Hoag’s identity.'
