The Goddess Venus is jealous of the beautiful human girl Psyche and blames her pet unicorn, Unico, for being Psyche's source of good luck. Venus has Unico banished, and it becomes his fate to forever journey from one place and time to the next, with the West Wind. Unico is a little unicorn who has the ability to make everybody happy. That is something the gods do not like, of course. So they send out the west wind to bring Unico to a place where he will never be seen again. The west wind, however, is unable to do so because she likes Unico too much and brings him to a lonely island instead. From there, the adventures and travels of little Unico begin.
