À nous deux, Paris!

Two ambitious young provincials, Patrick and Michel, go to Paris to seek their fortune. Patrick seems to be the epitome of the up-and-comer at any price: with no scruples whatsoever, he manages to break into the world of finance, i.e. into the home of banker Philippe Haguenauer. He soon becomes the lover of the woman, Hélène, director of a major fashion house, while Philippe, for his part, is having the perfect love affair with Nadine, his secretary. And this with the mutual consent of both spouses. Meanwhile, Michel, shy and sentimental, is looking for a situation, while remaining honest.
