 Bolshevik propaganda : the comparison between 1921 s Russia, and a capitalistic planet Mars. Engineer Los is building a spaceship to reach Mars. He is in love with Aelita, the regent, who he met in his dreams. In real life, his wife Natacha takes care of refugees. [Actually, Aelita is the figurehead queen, and not the regent (Tuskub), who holds the real power. Los s wife should be spelled "Natasha." -- Added notes by Prof S P Hill.]
