The police suspect that the man was deliberately abandoned in this place. Unfortunately, they don't find any documents with him. The injured person only has a characteristic chain with him, which the police officers take for analysis. It turns out that he is in the city with his wife. After interrogating her, the main suspect becomes a man who employs emigrants to do physical work and for whom the injured party also worked. Meanwhile, Juliusz decides to cheer up the new policeman.
