When car dealer Joe Glauning disappears from a campsite in the border region between the Netherlands and Lower Saxony, he leaves behind not only his identification papers and personal belongings but also traces of blood. It is clearly a crime—and a case for Chief Inspector Thorsten Falke (Wotan Wilke Möhring), who will have to cross the border to solve it. He is assisted in his investigation by cybercrime specialist Mario Schmitt (Denis Moschitto) and Dutch Chief Inspector Lynn de Baer (Gaite Jansen).
