Stephen King's Kingdom Hospital - Season 1 Episode 1 Thy Kingdom Come

Artist Peter Rickman is run down by a stoned, two-time loser driving a minivan. He is admitted comatose to Kingdom Hospital, but not before encountering a frightening, ghostly figure whose mission is to use him to rid the hospital of malevolence, both human and inhuman, and to free its nine-year old mistress, Mary, from the hospital's haunted halls. When he awakens in an altered state with newfound but not necessarily welcome telepathic powers, Rickman finds he can communicate with the spirits, good and evil, man and beast, inhabiting the hospital.
