Judge Claire Delval discovers that her father, Simon Delval, is involved in the corruption case she has been investigating for years. Forced to resign, his place in the Francophone Liberal Party is coveted by the discreet Mark Van Dyck

Music is the story of a father and son. Or, rather, the story of the reunion between a father and son who have hardly seen each other over many years and who clumsily attempt to renew bonds. Unfortunately, too much time has already passed and it will be impossible to strengthen the ties. But although they lose each other again, the father will nevertheless pass on a legacy to his son: the love of music.
