The ship of the good alien Zhdun crashed during a meteor shower and fell in the forest, not far from Abrau-Durso. Zhdun sends a distress signal into space and begins to wait for help, but there is a problem - his planet is 5 light years away and he would have to wait a long time. Fortunately, an inquisitive boy Nikita comes to Zhdun's aid, and later his whole family joins him. Nikita and the Semyonov family will have to help the alien repair the ship, avoid the machinations of a local swindler-businessman who passionately dreams of taking over alien technology, and return home. And Zhdun will re-teach the Semyonov family to hear and understand each other, and show that in an emergency, even an ordinary person can become a superhero.
