Tom and Annabel are a reasonably happy married couple. One evening they have an argument as to who loves the other most. A rough and tumble ensues, and Tom discovers to his horror that Annabel is dead.

So starts a hectic evening of black farce which also involves Tom's policeman and his literary agent. It seems no woman can enter the house without rapidly becoming deceased. Annabel's mother and Tom's appalling landlady follow and disposal of bodies becomes an acute problem. The arrival of a grim police inspector complicates matters until a further corpse involves him too.

The hysterical ending finds the stage littered with female corpses, frantic males and a potential fifth victim banging on the door.
