Winter solstice of 1936 and spring of 1937, Nanjing. In the name of "academic investigation", Japanese military cultural consultant Kono Masaki, in conjunction with the Shanghai Chamber of Commerce, systematically smuggled precious wooden components, mural rubbings and rare ancient books from ancient Jiangnan buildings. The driving force behind the scenes is the top brass of the Japanese army - these cultural relics will be used in the "Imperial Cultural Expo" in Tokyo to spiritually undermine the cultural confidence of the Chinese people.
Professor Song was silenced because he accidentally obtained the complete list. Starting from the remaining records, the four sisters peeled off the cocoons and uncovered a cultural relic smuggling network covering Ningbo and Shanghai. Their goal is not only to expose Kono, but also to prevent a batch of national treasure-level cultural relics that are about to be shipped to Japan.
