Each train driver kills more than 20 people in his career, usually as a result of suicide, error, drunkenness or simply carelessness. Elijah, a retiring train driver, killed 28 people. His 19-year-old adopted son, Sima, inherited his job. Sima was very worried that he would kill someone, and the old drivers comforted him that it would happen within a week, but a few weeks later, there was no collision, which made him extremely nervous. In order to help him, Ilya found many people who wanted to commit suicide and asked them to jump onto the tracks to commit suicide, but in the end, these people gave up the idea of suicide. In desperation, Elijah lay on the tracks and tried to save Sima with her own death.
