Felix is pretty certain his wife is up to something with her boss Dmitri, so he decides to hire some help to prove things one way or the other. When professional lip-reader Iris arrives with her powerful binoculars, the couple stake out a hotel bedroom and start to gather their evidence.
Inside No. 9 is a British dark comedy anthology television programme written by Reece Shearsmith and Steve Pemberton and produced by the BBC. Each half-hour episode is a self-contained story with new characters and a new setting, and all star at least one (usually both) of Pemberton and 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 fact that each takes place at a number 9, whether this is a suburban house, a gothic mansion or a dressing room.
