Michel is a musician and lives in a little village in Provence. His wife is Hungarian and they have a 24 year-old son, Balthazar, a violinist. Michel has been invited to play a concert in Budapest. He asks his son to help him. For Baltazar, this trip is a return back to roots. He is half-Hungarian, after all. For Michel, this is a great opportunity to staging a concert with old friends. This is a musical journey in space, time and spirit.
