In her determination to help her husband and friends, Dulcy plans a weekend party. They are an ill-assorted group, such as only a Dulcinea could summon about her. Their brief association becomes a series of hilarious tragedies. It is Dulcy's final blunder which unexpectedly crowns her efforts with success.

Meanwhile she has all but ruined her husband's plans to put through a big merger with a rich capitalist. Among her guests is a rapturous scenario writer who conspires to elope with the daughter of the capitalist, who loathes motion pictures. The rich young man from Newport, who Dulcy thinks may be useful in assisting the capitalist's wife to write for the films, turns out to be an escaped lunatic. The ex-convict butler steals a necklace. Everything goes wrong. But the most exquisite torture she inflicts is when she invites the scenario writer to recite one of his hectic plots to music played by the lunatic. It is with this that the play reaches its highest level of satirical fun.
