After an autumn storm, a skeletonized body is found under an uprooted oak tree. As Borowski suspects very quickly, it is the remains of his first friend Susanne. When Borowski was 16, he wanted to hitchhike Fehmarn with her for the legendary Jimi Hendrix appearance. After an argument, however, Susanne disappeared without a trace. Borowski had tried restlessly to clear up the disappearance. What was a grim assumption at the time is now suddenly bitter certainty when the forensic medicine Kroll unambiguously identifies the body. More resolutely than ever and without consultation with his colleagues, Borowski is pursuing the unexpected opportunity to face the perpetrator at the time after all these years. When Mila Sahin sees through this,she is shaken by the tragic fate of her colleague and initially covers him. But Borowski's constant going it alone finally forces her to involve her superior Schladitz.
