La dame de trèfle (The Queen of Clubs) follows Aurélien and Argine, an orphaned brother and sister who have spent their entire lives locked in an unusually close, codependent relationship. To keep them afloat, Aurélien secretly moonlights as a thief, selling stolen copper. But their fragile, isolated world begins to unravel when his unstable partner, Simon, goes on the run from the law and violently demands cash. Trapped in a dangerous downward spiral of crime and escalating hostility, Aurélien is forced to confront the harsh reality of the outside world—and the taboo, unhealthy attachment that keeps him bound to his sister.
