Wen Ruan, formerly a senior forensic examiner in the Forensic Evidence Division of the provincial public security department, quit after refusing to give false testimony in an old case appraisal. She opened an antique authentication studio for one purpose: to clear the name of her older sister, Wen Qing, who was falsely labeled a suicide 12 years ago. Lu Ze, the former leader of a major crimes squad, shows up with an autopsy report from that year that was supposed to have been destroyed. The two hit it off and join forces to solve one buried and maligned cold case involving women after another.
Trace evidence identifies the real culprit, while old clues piece together the truth. As they investigate, they repeatedly face suppression, threats, and online harassment. Moving from mutual suspicion to absolute trust, they become soulmates who fight side by side. As four unsolved cases are cracked one by one, the network of powerful protectors behind multiple wrongful convictions is finally exposed.
White roses for the dead, a glimmer of light to pierce the darkness. They should not be defined, nor should they be forgotten. Justice may have come late, but it will ultimately clear the names of all those who have suffered injustice.
