On a June night, environmentalist Piet Lorenzen disappears. The initial suspicion links his vanishing to the controversial oil drilling platform "Mittelplate A" which many locals in St. Peter-Ording despise. However, this is not the only lead that Marconi and his team – once again working independently – are following. Rumors suggest Lorenzen was about to inherit a lucrative property for which a real estate shark had offered him a fortune. And what about the argument with his pregnant girlfriend the night before he vanished?
Marconi is also dealing with personal chaos. His niece Klara is infatuated with Marconi’s arch-enemy Fabian Holthausen from the environmental organization GreenPlanet. Amid trying to be a good surrogate father, cooking "Labskausagne" (a mixture of the north German dish laubskaus and the Italian lasagne) with the kids, and facing challenges with the youth welfare office, Marconi must also contend with this tangled case. When a body is discovered, covered in oil and scattered with seagull feathers, the evidence in Lorenzen’s case converges into an unexpected tragedy.
