Just as 16-year-old Miki Witt is about to steal a few beers, he witnesses Lebanese clan boss Ahmed Sayed shooting an LKA officer. Even though the teenager is aware that he was seen doing it, he still decides to testify as a key witness. This is a difficult and courageous decision for his parents Nikola Walter and Klaus Witt, who live apart, and at the same time a great burden for everyone. In order to protect the family, the young police officer Sarah Brandt and her colleagues Marleen Westermann and Mario Lobeck are assigned to monitor the case. Despite all precautions, disaster strikes on site.
