Christophe Merignac, a youngESCP graduate with a law degree but still unemployed, gets a job as a concierge in a luxury building. Using charm and cunning, he makes himself indispensable. He makes a fortune and marries a young, pretty and rich tenant, whom he happily deceives. The conclusion is bittersweet: he's "made it", but he doesn't love anyone. What's more, a young concierge who looks like a brother has just arrived in his building.
