At the beginning of the 20th century, with the demise of the Qing Dynasty, a large number of palace treasures were lost to the public. The Beiyang government was unable to rule, which led to the coveting of foreign enemies and thieves, and the national treasures were in danger. The strong plot action drama "Imminent" tells the legendary story of this period, when people with lofty ideals spontaneously formed a private treasure protection organization "Wusha" to protect the treasure map that could find the 64 volumes of "Yongle Encyclopedia" that symbolizes Chinese civilization, and launched a fierce struggle with the evil forces of foreign powers such as Japan, the United States, and France.
