The movie was a massive hit at the French box office with admissions of 3,483,954.

Mr. Léon Martin, the incarnation of the average bourgeois, decides to buy a car.

Through this social encounter, the future of his daughter Mireille, in love with Paul de Grandlieu, must become clearer.

From this hope will come the obtaining of a driving license, the visit to the Auto Show, the hesitations over the choice of model, the deceptions of a hair-raising salesman, and the comical adventures of the hunt in Sologne.

Having returned from everything, Mr. Martin finally marries his daughter according to his heart and maintains his preference for the metro as a means of transport.
