Fyodor Zavyalov was nicknamed “the demonic soul” for his tough temperament. He received a sentence for a domestic stabbing and must atone for his guilt. In the camp, Fedor submits a report: he asks to go to the front. A penal battalion awaits him and a baptism of fire on the Kursk Bulge; he travels a long front road that is never smooth. It would seem that Victory is very close, but fate again tests Zavyalov’s strength.
