Mattia is 17 years old. Raised in a post-industrial province and experiencing an identity crisis, he is the son of a trade unionist and a housewife. Hypersensitive and fragile, he expresses himself through hip-hop music. The death of his older brother begins a period of great changes. Mattia leaves school, starts working in a factory and, through a North African colleague, approaches Islam. Prey to a lacerating restlessness, Mattia takes the path of progressive isolation and radicalization.
