The film continues the story of Maxim, who is now an idealistic revolutionary navigating political intrigue, labor strikes, and armed resistance in pre-World War I Russia, risking everything to ignite the spark of proletarian revolution.

In the lobby of the building where the Fourth State Duma of the Russian Empire is in session, various deputies from different social strata engage in dialogue, with many interactions portrayed satirically.

Standing apart from the crowd is Turaev, a member of the Bolshevik faction of the Social Democrats, who meets with Natasha, a party courier operating under the alias "Comrade Elena."

Maxim, now operating under the alias "Comrade Fyodor," leads a strike committee meeting disguised as a social gathering in a tavern.

The party sends Maxim to the front lines as a regular soldier, where he continues his revolutionary activities, conducting political agitation among the troops.
