Wildlife biologist Zhang Yunchuan pursues the missing endangered bear "A Yin" day and night, and breaks into the Southwest Nature Reserve following the collar's location. However, he accidentally confronts the circus heir Liu Nianchu with a gun. A few months ago, Liu Nianchu took a risk to rescue Ah Yin from a fire. At that time, she did not know that this mysterious dancing bear was actually a rare species.
During the investigation, Zhang Yunchuan discovered that A Yin's dance movements hid mysteries - each rotation and leap corresponded to the ancient code left by his grandfather, pointing to clues to the mysterious treasure. At the same time, the two were involved in the conspiracy of the poaching group. The genetic samples in the laboratory and the undercurrent of transactions in the black market were all threatening the safety of Ayin and the reserve.
When Ah Yin once again danced a familiar dance under the moonlight, the dusty family past and the oath of guardianship that spanned hundreds of years were revealed layer by layer. In a world intertwined with wilderness and neon, Zhang Yunchuan and Liu Nianchu went from tit-for-tat to fighting side by side. They not only wanted to unlock the ultimate code of bear dance, but also composed a touching love song that spanned species and time and space in a crisis-ridden adventure.
