Promotion canape

Catherine and Francoise, two young provincials with opposing temperaments, go to Paris to do an internship in the postal administration. They quickly realize that the best way to get a promotion is to give in to the advances of their superiors. Francoise refuses. But for her part, Catherine decides to play the game and very quickly obtains the favors of her superiors. Without knowing it, she arouses the jealousy of a colleague, Mademoiselle Poteau, who, to get revenge, has accused her of theft.
