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 an hilarious series of entrances and exits.
