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.
