Paul (Gregori Derangère), a promising young man from a modest background, arrives in Paris after being accepted into a prestigious Business School (Grande École). He moves into a shared apartment with Louis (Jocelyn Quivrin), an aristocratic, openly manipulative classmate, and begins dating Agnès (Alice Taglioni). As the high-pressure environment of elite corporate ambition and social hierarchy begins to take its toll, Paul finds himself drawn into complex power games, sexual bets, and shifting desires. A high-stakes wager involving Louis and Coralie (Salomé Stévenin) blurs the lines between social ambition, sexual fluidity, and emotional betrayal.
