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.

At the beginning of the summer of 1905, representatives of the Socialist-Revolutionary Party Krasilnikov and Elkonen turned to Captain Zhanis Trautman, a Latvian political emigrant living on the outskirts of London, with a proposal to lead a steamer with a cargo of weapons to the shores of Russia. Having recruited a team of old and tried comrades, Trautman changes the crew of an English cargo ship bought by the front men. In the course of the squabble that arose on this occasion, a sailor of the old crew, David Blake, was stabbed. The wounded Blake and the veterinarian Gruber, who accompanied the cargo of anthrax drugs, are forced to leave on board. On the high seas, weapons and explosives were loaded on board. The steamer headed for the Oresund Strait, where a messenger was to meet him.
