After Unico angers the evil goddess Venus, the brave young unicorn is banished-and all his memories erased. Rescued by the kind-hearted West Wind, Unico awakens in an unfamiliar world, where he's befriended by Chloe, an abandoned watch cat. Chloe begs Unico to turn her into a human so she can fend for herself. But that act of kindness has unforeseen consequences: Venus and her cutthroat henchman Byron seek to destroy them both! Time is running out for Unico to regain his memories and discover his hidden powers. If he does, then Unico may become one of the most powerful beings in the universe.
