In 1917, the Russian Revolution breaks out in earnest and Lenin and Krupskaya - now living in exile in Zurich - are both thrilled as the news finally reach them in Switzerland. They long to return to Russia and be part of the revolution, but at present they have no means of doing so. Kaiser Wilhelm of Germany - ailed and exhausted by war - is also very pleased and relieved by the news of a beginning revolution in Russia. In order to help the revolution on its way - in hope of removing Russia completely from World War I - he decides to secretly transport Lenin, Krupskaya, and other Russian revolutionaries back into Russia in a sealed train.
