Fabrège is a ladies' man. His friend Pascal, at the circle, evokes these conquests, among others Denise Lamblin for whom he fought a duel and this other woman for whom he stayed an entire night, in the pouring rain, under his windows. While the next day they have to take the train together, at the sight of a female figure on the station platform, Fabrège changes trains and sets out to conquer the beautiful stranger. Arrived in Cannes, they go down to the Miramar hotel and their idyll begins.
