Decades ago, horse thieves were rampant in Panyu. Although the ten tiger horse thieves were eliminated, the gold and silver treasures they looted were not recovered. The saying that there was a treasure buried in the area has been passed down. On this day, a Hong Kong auction house announced that it would auction a dog copper head, one of the twelve animal copper heads in the Yuanmingyuan Grand Fountain, which became a hot spot in the city; at the same time, the largest zoo in the country located in Panyu was accidentally unearthed during the expansion! For a time, the authenticity of the dog copper head caused an uproar. After university professor Zhao Xuewen (played by Hu Feng) went to Panyu for verification, he found that the dog copper head unearthed in Panyu was indeed a real dog copper head. It turned out that the legend of the treasure was true, and the other animal copper heads were also very likely buried nearby! Hong Kong tycoon He Zhengxiong has been committed to protecting national cultural relics. After learning the news, he funded Xuewen to find other missing animal copper heads. His grandson Junfeng (played by Chen Haomin) is talented, proficient in astronomy and geography, and has a detective mind. His grandfather hopes that he can stay in the mainland to inherit his career, but his mother hopes that he will return to Hong Kong to develop. In order to avoid offending anyone, Junfeng and his friend Jianxing (Tang Wenlong) temporarily come to work at the zoo. The group of young people make a lot of jokes at work, and Jianxing falls in love with the zoo's acrobat Lu Dan (Zhong Jiaxin). Zhengxiong asks Junfeng to help Zhao Xuewen find other missing animal copper heads, so Junfeng begins his treasure hunt.
