Dad was (in fact) one of the great pioneers in industrial efficiency and to his large family, "What works in the factory works in the home." His older daughters, however, rebel against their father. Anne, the oldest, strikes out for her independence but is unaware that her father has a heart condition. For this reason he is driving them toward super efficiency so the family will be able to survive better when he's gone. What Dad doesn't realize is that Anne has grown up. The breaking apart of Anne and her father and then their coming to a special maturity and mutual respect give meaning and emotion to what is otherwise a delightful and original comedy romp!
