4.5 million records sold, founding member of Söhne Mannheims and five-time Echo winner: Xavier Naidoo is one of Germany's most successful musicians. Filmmaker Harold Woetzel - himself from Mannheim - accompanied him. He has known Xavier Naidoo for many years and is therefore closer to the artist than almost any other journalist. It is a portrait of a great star, of his incredible love of his homeland and his roots in Baden-Württemberg's second largest city. The film shows how a song lyric is created from a small sound idea, shows Xavier Naidoo's collaboration with his closest friend Michael Herberger in the Mannheim studio. And it shows what an incredible success the idea of turning a group of friends of young multicultural Mannheim musicians into the Sons of Mannheim has become.
