Ivo is a bus driver in his fifties. His wife, Maja, is a housewife. Their son, Tomica, is about to graduate. They are satisfied with their normal and somewhat low-profile lives. Ivo is a gentle and quiet man and a law-abiding citizen. But even though he is living an ordinary life, he has strong moral principles. One day, Tomica comes home badly beaten-up. They go to the emergency room, but the doctor sends the boy home. Later that night, Tomica collapses. It seems that injuries are more serious than the doctor thought. Ivo and Maja become frightened and they go to the police but the police refuse to help. Bit by bit, Ivo is losing his trust in the rule of law. He used to believe that there are some principles on which society is built. Now he sees that’s not true. He decides he must do something, so he goes out looking for the boy who has beaten his son.
