Walentina (12) is the only one who wasn't allowed to go to summer camp during the summer vacations. Instead, she dreams herself to Planet Pax with a self-made rocket: a planet where there are no worries, loneliness or boredom. But the funny neighbor boy Juri (11) stands in front of Valentina's rocket and her dream slams full speed onto the asphalt. Only when the grumpy neighbor Sigmund sets his dog on the children does Valentina realize the truth about Planet Pax.
