There was a school. And one day, a parrot named Bořivoj came to the school and got all the A's for himself. The children - the pupils - can't just leave it like that, so Eva and Petr set off to the mysterious exotic land of parrots. Climbing, repeating old truths, chasing grades without regard to real knowledge and understanding - simply parroting - that's what the authors try to denounce in this musical comedy with humorous exaggeration.
