Da Cong is a seemingly unreliable tour guide. One day, he met Tong Tong, a young and beautiful female painter. Tong Tong came to Xishuangbanna according to the diary information mailed by her boyfriend Tianming. In the diary, her boyfriend told her that the two of them would play a love chasing game in Xishuangbanna without meeting each other. If Tong Tong successfully completed the game according to the plan in the diary, their love would come to fruition. Da Cong initially thought that this was just a joke between a man and a woman, but who would have thought that Tong Tong played it very seriously. Along the way, the two followed the map, experienced hardships, and made mistakes. After completing a series of tasks step by step, such as looking for paintings in the auditorium, hospital shock, hotel exploration, and looking for relatives in the cafe, they finally came to the end of the task in the diary, but found that Tianming had been buried deep under the cemetery. Tong Tong was heartbroken and wanted to die in grief.
