Psychoville is a dark character comedy mystery, starring The League of Gentlemen's Steve Pemberton and Reece Shearsmith, in which five different characters are strangely linked. 

The second six-part series, directed by Matt Lipsey, explores the aftermath of what happens when the characters return to the hospital. A locket with the letter 'K' on it becomes key. Police Detective Finney and shadowy Grace Andrews are amongst those who are desperate to get their hands on this item of jewellery.
