"La Couchette" is the first episode of the second series of British dark comedy anthology Inside No. 9. Written by Steve Pemberton and Reece Shearsmith and directed by Guillem Morales, the episode is set in a sleeper carriage on a French train. English doctor Maxwell, who is traveling to an important job interview, climbs into bed. He is disturbed first by drunk, flatulent German Jorg, and then by English couple Kath and Les. Later, while the others sleep, Australian backpacker Shona brings posh English backpacker Hugo back to the cabin, but the pair make a surprising discovery. The episode stars Pemberton, Shearsmith, Julie Hesmondhalgh, Mark Benton, Jessica Gunning, Jack Whitehall and George Glaves.

Inside No. 9 is a British black comedy anthology television programme that first aired on 5 February 2014. It is written by Steve Pemberton and Reece Shearsmith and produced by the BBC. Each 30-minute episode is a self-contained story with new characters and a new setting, almost all starring Pemberton or Shearsmith. Aside from the writers, each episode has a new cast, allowing Inside No. 9 to attract a number of well-known actors. The stories are linked only by the number 9 in some way, typically taking the form of a door marked with the number 9, and a brass hare statue that is in the background of all episodes. Themes and tone vary from episode to episode, but all have elements of comedy and horror or perverse humour, in addition to a plot twist. Pemberton and Shearsmith took inspiration for Inside No. 9 from an episode of Psychoville, a previous project, which was filmed in a single room – this in turn was inspired by Alfred Hitchcock's Rope.
