Vérotchka, a vivacious theater actress touring in a provincial town, is turned out of her hotel by orders of Monsieur Tricointe, the stern president of the local law court. In a rage, the actress knocks at Tricointe's door with a view to protesting against the treatment she is given. She goes about it so well that she ends up being accommodated by the president himself. This is the moment Jean-Pierre Gaudet, the Minister of Justice, chooses to pay an unannounced visit to his friend Tricointe. There he mistakes Vérotchka for Madame Tricointe and the president does not dare to contradict Gaudet. A lot of absurd situations ensue.

La célèbre actrice Verotcha est parvenue à se faire héberger pour une nuit chez l'austère président du tribunal d'une petite ville de province, Monsieur Tricointe. Une série d'imbroglios fait prendre l'artiste pour la présidente, ce qui jette la vraie présidente un ministre et une maîtresse jalouse dans des situations inextricables.
