Soviet cosmonauts land on the planet Venus and find it teeming with life, some of it dangerous.
Astronauts crash-land on Venus and find themselves in trouble when they kill a monster that is worshipped by a group of Venusian women.
This film consists of three parts. The first dramatizes the life of the founder of Soviet astronautics, Konstantin Tsiolkovsky; the second describes the development of rocket technology; and the third visualizes the future with enactments of the first manned spaceflight, spacewalk, space station construction and humans on the moon.
