Psychoville returns with a spooktacular hour-long Halloween special... which might try and tie up the myriad of loosely tethered strings after the series finale. What we're promised this time involves four tales of terror unfold as location manager Phil Walker investigates the abandoned ruins of Ravenhill Psychiactric hospital. Does the ghost of evil Governess Edwina Kenchington still walk the empty corridors? What other horrors lie within the crumbling walls and will health and safety allow any filming there in the first place?! Psychoville is written by and stars Reece Shearsmith and Steve Pemberton, as well as Dawn French, Imelda Staunton, Eileen Atkins, Daniel Kaluuya, and possibly a plastic baby.
