Case 137

Stéphanie (Léa Drucker), an investigator at the French National Police General Inspectorate (IGPN), is assigned Case 137, involving Guillaume Girard (Côme Péronnet), a young man left in a critical condition after being struck by a rubber bullet during a tense demonstration in Paris.

At first, nothing points to clear police misconduct — until Stéphanie discovers that the victim is from her own hometown, Saint-Dizier, turning the case into something far more personal.

As she digs deeper, reviewing surveillance footage, retracing movements, and interviewing officers, Stéphanie confronts the 'blue wall of silence' that shields the institution. The few who might talk, hesitate; those who know more, refuse to. Her only support comes from Alicia Mady (Guslagie Malanda), a chambermaid and reluctant witness whose testimony could unlock the truth — but puts them both at risk of retaliation.

Torn between loyalty and justice, Stéphanie finds herself increasingly isolated within a system determined to protect its own.
