Juri is an astronaut. When he returns to earth, he has difficulty coping with everyday life, everything just seems so mundane and narrow-minded. But he has other problems, too, time and time again he experiences relapses of weightlessness, even here on earth.

And then he meets Julika, who seems to have the same problems, except that she never flew into space. The two get along wonderfully, as if they were both from the same planet. The do the craziest things together. They fly to the moon, in an imaginary rocket. And unfortunately they have to return.
