By chance, construction workers discover a woman's body hidden under a road. During the murder investigation, the Bremen investigators Inga Lürsen (Sabine Postel) and Stedefreund (Oliver Mommsen) get caught up in a finely woven web of corruption and illegal financial transactions. They find out that the dead woman worked for a real estate development company. The company is in the sights of the BKA officials Maller (Robert Hunger-Bühler) and Kempf (Philipp Hochmair), who try by all means toprevent homicide investigations. Stedefreund also seems to be keeping important information to himself. Is it woven into the current case? And what is his relationship to Maller and Kempf? Inga Lürsen soon no longer knows who she can trust and who not. The last case becomes a heavy burden for the Bremen team. In "Where has my treasure gone?" Inspectors Lürsen and Stedefreund investigate their last case.
