Dying where others go on vacation. For village policeman Thies Detlefsen from the North Frisian town of Fredenbüll, summer vacation is approaching. As every year, the whole family is heading to Amrum. His wife Heike is looking forward to the wellness guesthouse, but there the twin girls immediately discover a dead golfer in the blue-and-white Frisian bed of their room. Before Thies can put on his service cap, the body has vanished again. Is the dead man real, or is the Hitchcock series at the island cinema stirring the imagination too much? Then two more bodies appear: tourism chief Heiner Griepenstroh and wealthy contractor Pohlmann do not survive the boisterous regulars' table at the upscale pub "Kombüse." This can only mean one thing: a serial killer is on the loose on the North Sea island!.
