The title character "Officer" is Tomasz Kruszynski "Kruszon" (Borys Szyc), a young police officer who works with his partner Rys (Andrzej Chyra) to break up a network of criminal connections.
Aldona (Magdalena Rozczka) appears next to them, a beautiful and independent woman. Together, they form a triangle full of tensions and emotions.
Kruszon is a symbol of the new generation of policemen. Seemingly a slacker from Warsaw's Praga, he is in fact an intelligent and crafty policeman. Perfectly finds itself in a criminal environment, which makes it easier for him to penetrate the mafia structures and to work them out from the inside.
Strong and unbending character and faithfulness to strictly set rules do not allow him to give in even in difficult situations.
