The young scientist Alexey invites his colleagues to present his invention. The real reason for the presentation lies in the teacher Alexey, whom he wants to publicly surpass.

The young gifted artist Ryabinin cannot stay away from the conflict in Donbass; he leaves his beloved girl in Moscow, a well-fed and calm life, and leaves for the civil war as a militia to capture the tragic events of Russian history and express feelings that only aroused anger in his bohemian environment; the suffering of people and the heroism of comrades completely change the consciousness of a young man - he loses his former attachments, grows up and finds himself.

Young scientist Alexey Romanovich invites all his colleagues interested in his experiment. 
Among the guests are collector, the member of the Scientific Council, also we see the father and son, who are devoted to science, 
but, clearly, have different intentions for the Alexey Romanov's experiment.
The real reason of the scientific project's presentation is the mentor of Alexei Romanovich - Pavel Egorovich.
At the scheduled time, everyone comes to the laboratory of young scientist.
