The War Train To Leningrad

Yesterday's Leningrad schoolgirl Masha Yablochkina, after a fierce blockade winter of 1941-1942, comes to the railway courses hoping to survive and gain strength. From there, the girl is sent to the construction of the Shlisselburg Highway, which connects the city with the Great Land and is in direct sight of German artillery. So the heroine gets into the 48th locomotive column of the special reserve NKPS, which at the cost of the deadly risk is to deliver to Leningrad 75% of all cargo and military equipment.
