This groundbreaking work of science fiction is… not really science fiction. It has sequences on Mars and iconic alien designs but most of the film is actually about an embezzlement scheme in the Soviet Union.
A mysterious message from outer space captures the imagination of a Russian scientist. He has other problems, though, as he suspects that his wife is stepping out on him with a petty official who moonlights as a black-market dealer. Oh yes, and there are scenes on Mars.
