This story, inspired by real characters, starts in Brussels. "Son Of" is the story of a gangster father (re)discovered by his children over the course of the episodes, while on a dangerous treasure hunt in the most hostile urban jungle in the world : Brussels. More specifically, it's the story of Camille, the robber's illegitimate son, who will have to find what his father - whom he has never really known - left behind : a heap of precious stones. Also the story of his best friend, Salim, who is going to help him (or is he ?) because, in fact, he would really like a normal life, well, almost; not really. And also the story of Sarah, the robber's daughter; the first two characters do not know her but must make do, because this «savage» is the only person who lived with their father throughout all those years on the run. And then, there is César, from the famous Matongé district, the nephew of a dangerous gang leader and Franck's youngest child who never met his father and who could turn out to be the key. Without a doubt, "Son Of" is a story of heritage. And the problem with heritage is that the bigger it is, the more people look for a share, and the more people look for a share, the more violent are the conflict. Circling the robber's haul are his daughter; his sons; his ex-girlfriend; the Dutch mafia; an African gangster; a mysterious mercenary - In short, many individuals. There is going to be trouble.
