 Events close in on Rosa Roth from one day to the other. Michael Katzmann, a criminal genius, is freed from prison in front of the eyes of the BKA and the BND (important German police institutions). He s supposed to plan a giant crime for Willem van Kleve, a weapon producer and international criminal. The BND-agent Adrienne Krayen starts to investigate Rosa, because she s suspected to have helped the escape of Michael Katzmann. After all it was her he wanted to talk to right before his escape. Rosa is completely left alone in a professional and private abyss. She s suspected of corruption after a big sum of money appears on her account. Karin von Lomanski, a colleague and friend, is kidnapped, Jürgen Röder, another colleague and friend, is being blackmailed and menaced, and Kubik, a colleague who feels deserted by Rosa starts to feel over strained and mistrusts her. Zorn, her boss, suspends her because of the pressure the BND puts on him. She can only hold on to her romance with Peter Nikolai , colleague from the securing of evidence department, but she doesn t realize that it s the enemy in her bed. Rosa is blackmailed by Karin s kidnappers and she s supposed to deliver them confidential information. It s a matter of life or death for her friend and colleague. Intuitively she senses that she s the victim of a conspiracy, behind which is hidden more than just private revenge. When Rosa finds out who is behind all this and what it s all about, it s almost too late to influence the events. But she s already so badly "hit", that she doesn t care about any losses and accepts the fight against her superior opponents.
