 A young American painter and his French wife move with their small daughter to the US when the husband s father dies. His mother takes an instant dislike to the wife, and when she finds out that her daughter-in-law is a nudist who once posed naked for an artist, she declares her son s wife to be an unfit mother and sets out to break up the marriage--which may not be difficult to do, as the son is a weak-willed "mama s boy" who s terrified to stand up against his domineering mother.
