Felizia Sanddorn, a journalist who wants to write a book about the third generation of the RAF, disappears without a trace. Her father turns to Georg Wilsberg and hires the private detective to find her. A clue leads to New York. There, Wilsberg meets a former terrorist who knows his client better than he is willing to admit. Is Felizia actually researching her father's history? And what kind of history is it: Was the father a committed RAF member or an agent of the domestic intelligence service? Before Wilsberg can uncover the truth, his client gets a bullet in the head. And the Münster private detective is to be the scapegoat. In the German winter, Wilsberg realizes that not only the RAF but also their hunters have skeletons in their closets. And that he must work hard to come out unscathed.
