A weird and wonderfully bizarre Japanese cartoon from the '30s. A young boy lives with his grandmother in a city where people use small airplanes to get from place to place. He drives a taxi plane, and during one of his travels he bumps into a bird that has been shot by the boy's latest customer. The bird, as well as a hungry bear he meets next, offer him a reward for his help. Men cause many problems for animals - is there a way to help them stay out of trouble?.
