Marseille, Bruno, 50 years old, good suicidal BAC cop for whom living is painful following a family tragedy. Alassane, 17 years old, a young black man from the cities, a studious student, will cross paths with two delinquents Farid and Enzo who lead him into a life that is not his and will find himself in the wrong place at the wrong time. Following an arrest that goes badly, Bruno will find himself at Alassane's bedside. Thanks to the complicity of Julie the nurse and a loving mother, a bond will be forged between these two characters who are completely opposed. Alassane, without knowing it, will allow Bruno to see life differently with a hope for the future. Farid and Enzo take us into human baseness, a rape of a young girl in a city cellar or of a homeless woman ready to do anything for a pellet of crack... Can this justify Bruno becoming as violent as certain delinquents with death as an accelerator tragedy of his work colleague, Djamel?
