A barrage balloon appears unexpectedly over a Bulgarian village. The startled villagers decide to knock it down with a fusillade. But the balloon flies off to the mountains. The villagers, armed to their teeth, set off after it. But they are not alone in this undertaking. There is another armed group that chases the 'wonder'. An argument whose property the balloon is breaks out between the two groups. It turns out that the balloon flew from Romania over the Danube River. In the turmoil following the argument, the balloon is destroyed. The police arrive and punish the villagers for meddling in other people's affairs.
