In a state correctional institute for teenage girls, Madame Appel, the superintendent, rules with an iron fist. The State appoints thirty-year-old Yvonne to evaluate the situation. The young woman is convinced that the girls should feel wanted rather than be constantly subdued and is accordingly determined to make Madame Appel change her methods of education.
