A body of a student is found in the port of Amsterdam. Van der Valk and his team are tasked to solve this case, but are somewhat distracted by the arrival of a new employee, the internet expert Job Cloovers. A second body is found later and the question pops up whether they are connected to each other or not. The investigation leads them to the Amsterdam art world and to the municipal politics.

When the brutal killing of a fashion vlogger is broadcast live, Van Der Valk and his team find themselves drawn into investigating the contemporary fashion world. They are soon immersed in issues surrounding ethical design and sustainability and uncover a world of lies, drug-taking and double-dealing that leads to a second murder, of a well-known fashion designer killed on the catwalk at the launch of her latest range. The search for anonymous street artist, Omega 616, whose bold graffiti statements seem linked to both deaths, eventually leads the team to unravel a darker truth about interconnectedness and insecurity as the net closes in on the killer. Separately, a past case comes back to haunt for Dahlman and Van Der Valk leading to a climactic shootout involving the entire team.
