Danka, like any boy of his age, has a real dream - he wants to become a great circus performer. But to his surprise, the parents were not happy about the dream, but categorically forbade even thinking about the circus. The offended boy escapes from the house and falls into the black box of the famous magician - this is how the fun adventures begin. The company for the trip was quite decent: the dog Bagel, a small kitten with the delicious name Sausage, the nagging rat Grymza and the funny rabbit Hocus Pocus, together with Danka, they set off to meet their fate. The motley company will have to get into the real country of cats Koto-Vasiya, dance at the ball at the mouse king and meet the very cunning Brother Fox.
