During the redevelopment and demolition of Jiangzhou City's old district, workers discover a set of bones sealed in the basement of an apartment building slated for demolition. Criminal Investigation Captain Lu Zheng leads the case and confirms that the victim is Su Mian, a nineteen-year-old university student who disappeared twelve years ago. As the investigation deepens, Lu Zheng uncovers a tangled web connected to Su Mian's death: a pharmaceutical company suspected of illegal drug trials, an old case deliberately buried, someone who has spent twelve years living under the identity of a deceased classmate, and a past his own wife, Lin Ruojun, has never mentioned. As the truth is peeled back layer by layer, Lu Zheng must choose between the law and personal ties, justice and family.
