Song of Heroes(Комсомол)

Soviet solidarity is strong in Germany where the Communist Party (KPD) marches under the clenched fist in spite of police harassment... Radio broadcasts reach all parts of the Soviet Union, including Magnitogorsk. On the steppe near the city, a family of nomads lives in their yurt. The father hears blasting: iron ore for the steelworks. Crushed ore and coke yield molten steel for the ladle. Stop-motion animation shows the bountiful tractor and freight car output of the future... A new blast-furnace is under construction. Accepting jobs at the site are women, ethnic minorities, and the nomad. An English-speaking engineer supervises; a young riveter learns his trade from an old hand... In the Kubass region, miners labour to produce the coal which becomes coke in Magnitogorsk... At last the blast-furnace is complete. Workers celebrate. A cheerful patriotic song is sung. Steel pours forth. The new day reveals a finished plant.
