There are 13 separate stories in the series, all of them related to a murder. In order for the reader to have a correct idea of the specifics of the series, I will tell the plot of the first story.
Parents have two sons. The eldest, we can say, is an exemplary young man, and the youngest from birth is a sociopath. He doesn't get along with his schoolmates, his teachers, his parents -- nobody. His goal is to destroy everyone he hates. He hates everyone. He tricked his father into giving him $10,000 for a trip. The boy actually bought a gun.
The father learned from his son’s diary that he was preparing a mass murder. To prevent this, he goes on a tour with the intention of killing him. But the son was more cunning, unraveled the father's plan and dulled his vigilance. As a result, the son arranges a terrorist attack at the school, kills several children and shoots himself.
The father becomes accused of aiding his son in organizing a terrorist attack. He is tried, but the judge makes a decision - innocent.
During the terrorist attack, the son talks to his father on the phone through a negotiator, and his son reproaches him for not killing him on a tour. So does the wife (who has always protected her sons). After the trial, the first thing she said to her husband was, "Why didn't you kill him?"
The rest of the series is like the first. The situations are different, but the defendants were forced to do what they did or were accidentally involved.
I watched 6 episodes, and then my psyche could not stand the viewing.
