Since his arrival in France as a child, the traumas of exile, abandonment, and poverty have shaped the identity of Alix Mathurin. As a teenager, rap and the streets led him away from school. Endowed with a strong presence and a sensitive pen, Kery James quickly becomes the voice of a generation of young people from the suburbs who are aware that life and they themselves are deteriorating together. At the same time, he plays with fire within a gang of drug dealers and robbers. The murder of one of his friends prompts him to stop everything, both rap and the path of delinquency. Converted to Islam, he resumes rap as a missionary because he knows that his voice is influential.
