Weaver's story that tells of Flagg Purdy, a thrifty man who won't pay the county phone tax and won't let his wife and 11 children celebrate any holiday. He rules their lives by his principles, but something has just happened in this well-ordered universe. Purdy's favorite daughter has decided to get married and celebrate the winter holiday season with a tree and presents. As Christmas comes to the Purdy household, the serious, and often funny, family confrontations that follow sow the seed of women's liberation and face Purdy with the question of whether love is more important than pride.
