Two chickens who seem out of place try to make a home for themselves on an island populated by cranes, where crane parents take them in. When an eagle attacks, those adoptive crane parents are killed. The chickens respond by organizing a counterattack, and in time peace returns to the island. Based on a story by Teru Takakura, the film is a sincere tale of animals working together, produced over three years by roughly 80 members of the Japan Film Broadcasting Industry Association, led under the pseudonym Shibayama.
