Moon Bear is about an 11-year old boy named Tam who moves to the city to earn money for his family after his father dies. While he is living in the city, he has to work at a bear bile farm. A bear bile farm is a place where the workers extract bile from bears to sell it as medicine. After a while he meets a special type of bear, a nearly endangered “Moon Bear” also called the Asian black bear. Tam recognizes this bear from when he encountered it earlier in his village. He had met this bear when he went hunting with his best friend Noy, the village chief’s youngest son.
