The events unfold in 1915-1917. Marxist theoretician and publicist Alexander Parvus, who fled to Germany from a Russian exile, during the First World War has been successfully negotiating with German Foreign Minister Gottlieb von Jagow. As a result of negotiations, the German government allocates money to Parvus personally for organizing a revolution in the belligerent Russian empire. On the funds received Parvus finances and remotely stimulates protest actions of the popular masses in St. Petersburg, which leads to the abdication of the power of Emperor Nicholas II and the overthrow of the monarchy in the Russian Empire. Then Parvus organizes the return to Russia of the emigration of the leader of the Bolsheviks, Vladimir Lenin, with a group of his associates. Parvus' actions are being resisted by the head of the Russian imperial counterintelligence, Prince Vasily Turkestanov, and counterintelligence officer Alexei Mezentsev.
