The good fairy Rosabelverde, out of pity, bewitches Tsakhes, who is ugly in body and soul, so that most people stop noticing his ugliness. Now people are drawn to him. Any praiseworthy deed done in his presence is attributed to him, Tsakhes, who changed his former name to a new one - Zinnober. And vice versa, if he meows disgustingly or stumbles, someone else will certainly be guilty. Thanks to the gift of the good fairy, the dwarf enchants Professor Turpin Mosch and his daughter Candida. Only student Balthazar, who is in love with a beautiful girl, sees the true appearance of the villain.
