Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, Moko crosses the plains of Siberia and gets his first taste of the cold. After having found shelter in a cave for the night, he wakes to find a carpet of snow stretching out over the landscape as far as his eyes can see. Amazed at first, Moko realizes that he can no longer see his path and find his way. Could he have found the end of the world where distracted travelers get lost? At which point he notices footprints leading to a village.
