Newly promoted traffic police sergeant Anton Prokofiev arrives at post No. 376 to serve. Anton is eager to fulfill his official duties in an exemplary manner, but his mentor, Sergeant Major Belyaev, whom everyone simply calls Semenych, is in no hurry. Semenych is afraid that the young, hot-headed traffic cop will screw something up from excessive zeal. And just then an order came to inspect a spaceship, the crew of which was suspected of transporting prohibited substances. The matter becomes more complicated when, at the indicated time, instead of one ship, three appeared. And, as luck would have it, each one contains items that can be considered contraband! After all, even an ordinary refrigerator magnet is considered a weapon on some planets! So the servants have to get out of it... However, in the everyday life of the Hyperdimensional Astroinspectorate, this is not what happens...
