The main theme of the cartoon is the concept of Enlightenment and release from the yellow mist of civilization. This is a story about a little hedgehog (voiced by Mariya Vinogradova) and his friend bear cub (voiced by Vyacheslav Nevinniy). The two would meet every evening to drink tea from the cub's samovar, which was heated on a fire of juniper twigs. As they drank their tea, the hedgehog and the bear conversed and counted the stars together. One day, the hedgehog decided to bring raspberry jam. As he went to the bear to count the stars, he passed through the woods and found a horse standing in a fog, where the hedgehog can't even see his own pink paw. He is curious as to whether the horse would drown if it went to sleep in the fog. The hedgehog decides to explore the fog.
