The king Serendippa Deramo wants to get married, but does not know how to distinguish between the genuine love and flattery. To help him, the magician brings a wonderful "doodle", who can accurately distinguish a lie, to the court, but. But then a wonderful fairy confusion began: the First Minister Tartaglia appeared in the doodle's place, in the Queen's place - instead of the treacherous minister's daughter, there was a girl Angela, who was the Minister in love with, so the villain Tartaglia had to dodge and take the place of the king himself, along with his body, forcing mistrustful Deramo into a body of a deer, doomed to become a victim of hunters.
