“Horsemen From Nowhere” is a science-fiction story about the arrival on earth of mysterious rose-coloured “clouds” from deep space. Members of the
Soviet Antarctic expedition are the first to meet them in a series of inexplicable events. The “clouds” are seen to be removing the Antarctic
ice-cap and carrying it off into space. They are capable of reproducing any kind of atomic structure, and this goes for human beings as well. The heroes
of the story meet their “counterparts”, come upon a duplicated airliner,
journey through a modelled city, and fight Gestapo policemen that have been
reconstructed from the past by these same mysterious “clouds”. Scientists
are not able to explain why terrestrial life is being modelled. All attempts
to contact the space beings fail. In the end, however, Soviet scientists
penetrate the enigma of the rose clouds and establish contact with a highly
developed extragalactic civilization.
