A couple (Jian RenZi and Andrew Lin) who has been unsuccessfully trying to have a child for a few years, and decides to resort to an old Chinese fertility ritual, that of the “primer”: to temporarily adopt a child, who will open the way for their own progeny. They adopt a quiet 7-year-old girl (Wang Yifei) at an orphanage whose supervisors (Hui Shiu Hung and Pat Ha) are obviously not telling them everything. The adopted child is silent, asocial and constantly draws disturbingly dark pictures of her previous family. It doesn’t help that her new mother is beset with strange visions that threaten her sanity.

In the early days of the founding of the People's Republic of China in 1949, New China was faced with "internal and external troubles". Since the outbreak of the Korean Civil War, the U.S. military has repeatedly provoked the border between China and North Korea, and civilians have been brutally bombed. In order to maintain the hard-won peace and long-term stability for generations, in October 1950, the Chinese People's Volunteers entered North Korea, and the "Resist US Aid Korea" war kicked off.
