An aging zoo keeper, Toshio Nishiyama, takes on two young trainees: Takeshi Ishizawa, a short‑tempered former chef, and Ichiro Hasegawa, a gentle vet. Though the job seems simple at first, they are confronted with a string of challenges, including an escaped pelican, a dying camel, and the birth of a hippo, and they persist through the difficulties. The semi‑autobiographical TV special is based on anecdotes from real‑life Tobu Animal Park zookeeper Nishiyama, who appears at the beginning and end of the program to discuss his love for animals and to reveal that Ishizawa is, in fact, a projection of his younger self.
