Elbrus Tamayev, a guy from a working-class family, was brought up in the spirit of fundamental male principles: not to offend the weak, to be able to fight back and help those in need. During his school years, he makes a friend and a girlfriend. Elbrus gets a job on a dry cargo ship. His friend pulls off a drug scam. It is exposed, and Elbrus becomes the scapegoat in this case... He is sentenced to life imprisonment in a prison for especially dangerous criminals, from which it is impossible to escape. But the hero - now his name is none other than Graf Krestovsky - succeeds twenty years later. He returns to his homeland and begins to take revenge on those who treated him so cruelly.
