Yura had a bad day on his birthday: he got a bad grade. And the adults around him were saying some strange things: “You’re driving me crazy! Stop being lazy! Get this into your head!” Yura and his friend Katya are trying to figure out where these mysterious expressions, called phraseological units, come from.

Little heroes Yura and Katya, thanks to a magical gift from Yura's grandmother, find themselves in an extraordinary land of knowledge where there are no boundaries. In this land, you can travel anywhere and learn a lot. The children decide to learn about the oceans. Together with their all-knowing assistant, the heroes set off on a journey across four oceans: the Pacific, Atlantic, Indian, and North.
