The upper echelons of 1930s English society have gathered at a house party, but tea and pleasantries are cast aside when one of the guests reveals that she has been conducting an experiment. When her wild claims are proved to be true the birthday weekend is thrown into murderous chaos. Can the cat be put back in the bag? Will there be crying over spilt milk or spilt blood? At the end of the weekend, who will live to tell the cat's tale?
Based on the short story ‘Tobermory’ by H.H. Munro, this black comedy of manners examines the intricacies of the love between pets and people.
