A young man is looking for his father who is a judge. His father had previously had a sexual encounter with a young lady who the young man knows. She is demanding that the judge resign from his position, or she will press charges. The judge asks his son (not knowing he is his son) to kill the girl, and gives him a picture and the information in an envelope. He throws the envelope away, but his friend finds it, and goes to kill the girl for the money.
