An eccentric musical comedy based on the tale of Korney Chukovsky.

In Africa, monkeys fell ill. This news was reported to Dr. Aybolit by the monkey Chichi, who escaped from the robber Barmaley.

Aybolit and his assistants — Chichi and the dog Avva — are in a hurry to save the monkeys from the disease. But Barmaley and his robbers are trying to stop them. First, they capture the doctor’s ship at sea and throw Aybolit, Avva and Chichi into the water, but they swim to Africa.
