Poorly educated by her father, a wacky researcher, Claudine is a teenager full of life who loves her small village school run by Miss Sergeant. A new teacher, Aimée Lanthenay, arrives at the school. Seemingly awkward, she is actually an arrivist who manages to get the departure of Miss Sergeant.
Jules Vachon, a pharmacist, has two sons, Gabriel, a steady-minded young man dedicated to his job in the pharmacy, and Gaston, a good for nothing whose only talent is to seduce rich women and take money from their pockets. But it is Gaston who is hailed as a great man when he returns to his native village thanks to his deep pockets.
Somewhat reminiscent of 'Mädchen in Uniform' (1931), the story is set in a private girl's school, populated almost exclusively by children from broken homes. Among the few students who can claim family stability is Micheline Presle, but even her happiness is threatened when her lawyer father Andre Luguet inaugurates an affair with stage actress Jacqueline Debulac. With the help of Debulac's daughter Louisa Carletti, Presle is able to break up her father's romance and deliver him into the open arms of her mother Marcelle Chantal.
