"Undercurrent: 1983" uses two intertwined lines to reveal a genetic conspiracy that spans forty years. In 2025, when researcher Lin Xia was thawing the biological samples left by his father Lin Zhengyang, he discovered that his "accidental death" in 1983 was actually related to human experiments in the Northeast Military Industrial City. The titanium alloy debris and mutated gene map in the bloodstains in the cold storage connect the "Human Evolution Project" that my father investigated during his lifetime - a top-secret project that uses aerospace metal to transform bones and uses prions to catalyze gene mutation. The splicing gene awakening in Lin Xia's body and the sarcoma growing wildly on her shoulder blades imply that she has long been reduced to an experimental vessel. In order to prevent the rampage of genetic weapons, she followed the film map and binary code left by her father and broke into the underground restricted area of the military factory. However, she witnessed the truth that two generations were controlled by the same "hand of the creator": from the bloodbath of the laboratory by special agents in 1983 to the harvest of mutation results by multinational groups today, the so-called human evolution is nothing but a slaughterhouse colluding with power and capital...
