In China's Chengdu Park, a group of scientists are working to preserve and breed pandas, some of the funniest mammals on our planet, which are unfortunately on the verge of extinction. After the positive experience of scientists from the United States in adapting black bears to the wild, the Chinese scientists decide to apply this technique to another mammal species. Baby Chen Chen, born in a panda orphanage, becomes the first participant in this exciting experiment to explore the unknown.
