In 1994, a pregnant wife and daughter of a literature teacher were killed in Chechnya. Beastly, he converted to Islam and went to war against the Russians. The teacher mocks the prisoners even more severely than the Chechens themselves: yes, he pierces the eyes of one of his compatriots ... In Moscow, a "blind" killer kills Caucasians with a cane: so he decided to take revenge on his brother, who was left without eyes after the war. A strange series of murders is being investigated by a law student who is undergoing a police internship.
