S2, E3: Crime drama. When classical musician and former musical child prodigy Fleur Mas is the victim of an acid attack and subsequently dies, Van Der Valk and his team must question if the intention of this attack was to maim and disfigure or to kill. As the attack took place in a crowded concert hall foyer with numerous witnesses, was the attacker trying to send a message? The investigation takes an unexpectedly personal turn when Brad and Job interview the victim's partner Femke De Haan, a guest conductor who also happens to be Lucienne's ex. Rehearsing for their annual performance on the canal, the orchestra is raising money for No To Silence, a charity that supports victims of sexual assault and encourages those affected to come forward. The investigation ultimately brings Van Der Valk and his team face to face with corruption and coercion at the highest levels of authority to discover an international sex trafficking network that has links all the way to the top.
