1917. In Petrograd, a young Latvian boy Jezups signs up to work for the revolution and is sent to central Russia to show films and campaign for joining the Red Army. Jezups is a naive idealist and would rather not touch weapons at all, but life destroys his belief that it is possible to do without violence. In the end, Jezups is forced to understand that the ideals of the revolution must be defended not only with a film projector, but also with a machine gun.

The son of Martins Viksna, the collective farm chairman, Klavs comes home from the military service and starts working in his native kolkhoz but does not understand his colleagues, so he goes to town.

About the family of the old man Achila-Buva, about his children and grandchildren living in an Uzbek village, about an old plane tree covering the saplings with its branches.

The events of the film take place in Latvia during the 1930s to the 1950s. Klinta, a young, poor, and naive villager, studies music in a nearby provincial Latvian town. Her meeting with the owner of a wealthy farm, Olavs, becomes fateful for the girl.
