A mystery writer rents a New England house that is the rendezvous point for some jewel thieves. The focal point of the set is the closet, which opens into a living room and a library. A body found in the closet promptly disappears only to be succeeded by another. The hunt for the jewels reaches a climax at two A.M. when four couples unknown to each other turn up to search. Not since the days of Mack Sennett has there been such a hilarious series of entrances and exits.
