When the family is hungry, they have to be fed. But a ready-to-please mom finds out that there is apparently no limit to the appetite of her husband and children. The more she cooks, the more they eat. Even the announcement of a class reunion, at which mom and dad would like to appear in their finest form produces only half-hearted attempts to get a little exercise. Only when their daughter learns a thing or two about calories and returns to take charge of the kitchen is there a change in eating patterns.
