At the "Pupky" station, an opportunity occurs: two illegal passengers - guinea pigs - have to be disembarked from one of the trains, since animals cannot be transported in a general carriage. The head of the station Pryvychkin tries to help the animals, but the situation is beyond his control. The audit committee sets out to investigate the unpleasant incident... This witty satirical comedy, in which bureaucracy, bourgeoisie and provincialism are mocked, continued the development of the domestic comedy genre in Ukrainian Soviet cinema.

Several teenagers in a small-town in Colorado concoct a July 4th prank based on a frightening legend that goes awry when their friend ends up accidentally killed; however, the teens agree to keep their involvement a secret from the authorities, who continue to search for the man who apparently killed their friend. A year later, with the July 4th celebration coming up again, the teenagers realize that they're being stalked by someone who clearly intends on keeping the horrible legend alive by killing them off.
