Claire (Anne Brochet) is a 38-year-old bank litigation officer who leads a comfortable life with her partner Antoine (Thomas Jouannet) and her teenage daughter Lola (Alice de Lencquesaing). Her world is upended when a severe debt case lands on her desk belonging to Jacques Marey (Johan Leysen)—the man who was her intense first love twenty years prior. Finding Jacques broke and struggling, Claire arranges for Antoine to take in Jacques' son, Julien. Reconnecting with Jacques rekindles unresolved emotional and physical passion, driving Claire into a secretive extramarital affair behind Antoine's back, while Lola begins navigating her own romantic fixations.
