Collini (Franco Nero) is an old worker who has worked diligently for decades. One day, he surrendered to the police, claiming that he had killed a man named Mayer (Manfred Zapatka). Ryan (Elyas M'Barek) is the lawyer responsible for defending Collini. This is the first case he has taken on as a rookie. In fact, Mayer is an old acquaintance of Ryan, and Ryan has received a lot of care from the former. At the same time, Ryan's opponent Richard (Heiner Lauterbach) is a very experienced court veteran. In the process of finding the truth, Collini has always remained silent, which makes Ryan's work nowhere to do. However, as the investigation progresses, Ryan finds that what he wants to uncover is a huge black curtain shrouded in the history of German justice.
