A story about one of the key and significant operations of the Great Patriotic War - Operation Iskra. Since this is just a short story, its purpose is not to reveal the whole idea and plan of this large-scale offensive operation to lift the siege of Leningrad, not to show its entire course, but just to try to tell about the people, about the Soviet soldiers. About those who, sacrificing themselves, broke through this deadly ring that squeezed the city of three revolutions.
