Elizabeth Rimplegar inhabits a household populated by virtual lunatics. Her mother, Nellie, mishandled the family fortune, and, alas, the stock market crash has depleted their worth. Elizabeth's goofy brothers cannot easily adjust to the life of the average worker. Meanwhile, the family doctor has his eye on Elizabeth, but he will have to compete with her suitor, an ill-informed writer.
