Makar Veselov is happy: finally his parents bought a dacha, and even in an amazing village called the Seven Wonders of the World! But on the very first day of the long-awaited vacation, it turns out that Makar, his older sister Sonya and his younger brother Ladoshka will not have to rest, but will have to look for their pet, honor boy Nyuk. The guys understand that Honorika could have been kidnapped by any of their unusual neighbors - the owner of a collection of microscopes and telescopes, the owner of a menagerie with exotic animals, a strange aeronaut, or someone else?.. In order to save Nyuk from mortal danger, Makar has to use sneezing powder , watch the otter and monitor lizard, fly over the village in a hot air balloon... And yet he would not have been able to expose the unknown attacker if Nyuk himself had not helped his master. It’s not for nothing that the guys consider Honorik the eighth wonder of the world!..
