When the HR manager of a Stuttgart company is found dead in the forest, the inspectors Thorsten Lannert and Sebastian Bootz begin their investigations in the company. They hear no special incidents - CEO Joachim Bässler does not mention his conflict with former employee Oliver Manlik. He was imprisoned for corruption in the USA for over three years as a pawn by the company. Now he's back in the country and wants his life back. His private life is in ruins, his wife Caroline has lost all trust in him and his son also evades him. At least at the company, Oliver Manlik wants to achieve something. Reinstatement and compensation for his imprisonment are the bare minimum for him. Bässler's consistent rejection, trimmed for efficiency, continues to incite his feelings of revenge. When a bomb attack is carried out on the CEO's car, he is convinced that Manlik is the culprit. Suddenly he found it convenient that Manlik is considered the chief suspect in the HR manager's case. However - Thorsten Lannert and Sebastian Bootz have not yet found evidence of this. But it is clear to them that they have to prevent an escalation of the fight between the increasingly desperate Oliver Manlik and the less scrupulous Joachim Bässler .
