Suave French actor Philippe Martin provokes a scandal when, in a darkened theater, he mistakes young Monique for his mistress, Yvonne, and tries to kiss her. Charged with assault, the quick-thinking Philippe claims it's French tradition to do as he did, and is let go. To his surprise, Philippe learns that Monique has paid his fine. As the tabloids exploit the situation, Monique dates Philippe, until a photo appears of him kissing Yvonne.
