Two friends - Victor and Anton, employees of a Moscow construction company - find mysterious pendants on the street. For fun, they put them on and discover that the pendants are capable of transporting their owner anywhere. At least inside a locked bank. Victor immediately took advantage of this property and got into trouble with the law, and even framed his friend. And then two Ivan Andreevichs come out to Anton. One is a police investigator. And the other... Fortunately for himself, Anton Bogatyrev met someone else. Ivan Andreevich number two offered him a new job: to become an interstellar courier. Anton, of course, agreed; he passionately loved to travel. How could he know that the fate of the entire Galaxy depended on a modest interstellar courier?!
