Anthology show featuring darkly comic tales, each of which takes place inside a building or apartment marked number nine. Whether in a grand country house where an innocent game leads to chilling revelations, a primary school teacher's one-bedroom flat, or a historic village in the grip of a witch hunt, the buildings are the sites of tales with unexpected twists that, in many cases, take a turn for the horrific. All of the stories come from the minds of writers Steve Pemberton and Reece Shearsmith, who also star in some episodes.
