An anonymous letter on a stormy night shatters Jiangcheng’s peace. Reporter Shen Zhiyuan is attacked by a mutant at an abandoned waterworks, accidentally uncovering a genetic conspiracy behind his girlfriend Lin Xiaoyu’s car accident. The Cleaners claim to “eliminate out-of-control mutants,” but are actually conducting human experiments in partnership with Entropy Group. Xiaoyu is Experiment 073, the one who holds crucial evidence.
Following the clues into the underground laboratory of People’s Hospital, Shen Zhiyuan discovers that Jiang Wantang, leader of the Cleaners, bears the same gray markings as the mutants. As his investigation deepens, he gradually uncovers the terrifying truth behind Project Undertow: Entropy Group CEO Lu Chen intends to activate dormant human genes with an improved virus. The success rate is only 3 percent; the other 97 percent will become mindless monsters. Jiang Wantang, the first successful result of the Cleaners’ program, is under Lu Chen’s control and has become the perfect vessel for genetic experiments.
On the run and fighting back, Shen Zhiyuan joins forces with Gu Beichuan, a former Entropy Group scientist, and an underground mutant organization on a desperate journey to expose the truth. From the gene black market at the western docks to the final showdown at an offshore laboratory, he must stop the virus from being released within three days, while also uncovering the mysterious connection between Jiang Wantang and Xiaoyu. Who is really controlling humanity’s evolution and destruction from behind this genetic hunt?
