The film tells about the creation of the first collective farm communes and class enmity. Vasyl, a member of the Komsomol, with the help of a local party organization, gets a tractor and plows private boundaries "on kulak fields." However, this enthusiasm will cost him dearly.

The film recreates the events of 1905. In the center of the picture is the struggle of the proletariat, led by the Bolshevik party, against tsarism. The demonstration of labor unrest is replaced by episodes of the Russo-Japanese war, Black-Hundred demonstrations, accompanied by a pogrom of Jews, and beating of the intelligentsia. The film paints the attitude of the Mensheviks towards armed insurrection, reproduces the picture of barricade battles, the arrest of the Council of Workers' Deputies and the brutal reprisals of the tsarist autocracy with revolutionaries.

The end of the 1920s. The capitalist world is in crisis. The fascists unleash war against the Soviet Union. The enemy attack interrupts the peaceful labor of Soviet people. Hundreds of production workers join the Red Army. At the front go Red Army units, columns of tanks, units of the people's militia. Enemy airplanes appear over the Soviet city, black bomb bursts are rising. The streets are moving mournful funeral processions of the first victims of the war. At the end of the movie, a worker appears on the screen, appealing to the audience to be ready for the war, which has not yet come, but will come “maybe tomorrow"
