The Kiel author Dirk Sauerland is found dead on his yacht. Sauerland was known beyond the borders of Kiel. In recent months he had been working on a spectacular disclosure story. Sauerland's ex-wife Ulla Jahn, who hosts a popular talk show, gives Chief Inspector Borowski and Inspector Sarah Brand a hint about the dead man's gay double life. What interest does state politician Karl Martin von Treunau have in his relationship with the dead man?hide? A contact sheet with photos from the 1980s puts Borowski on an old track. 25 years ago, Schleswig-Holstein Prime Minister Uwe Barschel died in a hotel in Geneva. Apparently Dirk Sauerland was there at the same time. What did he discover back then, and why did Sauerland have to die today? Sarah Brand throws herself full of zeal into researching the Barschel case. Borowski prefers to remain a realist. Then suddenly a witness from Geneva appears.
