A film about animated monkeys making a feature film.

Doctor Aybolit blasts into space accompanied by his faithful companions, the talking monkey Chichi and the talking dog Avva, hot on the trail of his arch-nemesis Barmalei, a pirate who has kidnapped a group of simian children. Meanwhile, in animated framing sequences, a fast-talking film producer pitches this tale to a studio executive with a personal stake in the story. The live-action scenes were taken from the 1966 Soviet children's film "Aybolit 66."
