The story follows Madeleine (Rebecca Marder) and Antoine (Benjamin Lavernhe), a young, ambitious couple with staunch left-wing convictions. While preparing for their ENA exams in Corsica, a sudden, violent encounter on a deserted road leads to a fatal accident: Madeleine kills a man in self-defense. Terrified of ruining their future careers, the couple decides to flee and keep the death a secret.
Rebecca Marder is widely praised for her complex portrayal of Madeleine, depicting a "grey morality" that is both sympathetic and chillingly aloof.
Reviewers at AlloCiné and Sortir à Paris note that while it starts as a psychological drama, it evolves into a diabolical "social tale" about how far people will go to protect their ambitions.
Months later, both have successfully entered the world of high-level politics—but they find themselves working for rival figures. As their careers take off, the burden of their shared secret begins to poison their relationship and threaten their political survival.
