Public prosecutor Judith Schrader wants to return to the 'Organized Crime' department. She has been given a chance to do so, as Sirin Dogan is to become the new police commissioner. The politician of Kurdish descent takes action against right-wing extremism, especially within the police force. This makes her the target of hatred. Shortly before her inauguration, a stranger threatens her with death in her apartment. Judith accepts the assignment to investigate this stranger and once again works with Detective Chief Inspector Jochen Montag.

Unable to stand by and watch as countless refugees lose their lives attempting to reach Europe by sea, a group of young Berliners take action.

But their efforts soon put their understanding of law and justice to the test.
