The body of Christian Rommedahl, from Denmark, washes up on the Flensburg Fjord. The victim's friend and work colleague, Lasse Jørgensen, is the target of the new investigator duo Svenja Rasmussen and Antoine Haller. Another lead leads the inspector to the Flensburg liquor dealer Philipp Schaaf. There also seems to be a connection between him and the dead. Because photos of Schaaf's daughter Lisa are found on the dead person's cell phone, and Lasse also seems to be involved.
