Widowed at the age of twenty, Madame Boissière is a real mother hen, excessively brooding over her two sons Robert and Claude. She spoiled the marriage of one and kept the other away from any female presence. The latter runs off and marries a girl from the mountains. When his brother dies, the couple agree to return to live with Madame Boissière, who tries to separate them.
