Une bonne leçon

Sidonie comes back from Morocco nursing a broken heart after a relationship with a man named Diego goes wrong. Her sister Marion, a Parisian lawyer, decides she can't let Diego get away with what he did and goes to Morocco to teach him a lesson. The film follows Marion as she confronts the situation, balancing legal savvy, family loyalty, and the messier human emotions that surface when private pain turns public. There are tense confrontations and quieter moments that reveal why both sisters act the way they do, and the story keeps the focus on character choices rather than cliffhanger plot twists.

Directed by Bruno Garcia and created by Luc Chaumar and Claude-Michel Rome, Une bonne leçon is a 2013 French television movie starring Ingrid Chauvin, Frédéric Diefenthal, Jean-Michel Dupuis, Blanche Ravalec, and Stéphanie Pasterkamp.

As a TV movie it didn't have a theatrical run, so there are no box office figures to report. Its reach depended on broadcast viewership and later distribution through television channels and on-demand platforms rather than cinema grosses.

While it didn't leave a wide cultural footprint beyond French television viewers, the film taps into familiar genre beats from domestic dramas, and its casting of well-known TV actors helped it find an audience among fans of French small-screen drama. Scenes of legal confrontation and family argument are the moments viewers most often recall.

Critical and audience reaction was mixed, reflected in a modest average rating around 5.5 out of 10 from a small number of votes. Reviewers and viewers tended to focus on the performances of the leads and the film's look at family loyalty, revenge, and the ethics of personal justice, saying the story worked better when it stayed grounded in character than when it relied on melodrama.
