Premise and structure

The drama follows Sergeant To Kai-bun (杜凯斌), played by Michael Miu, and officer Yim Cheuk-wing (严灼颖), played by Eliza Sam, of a Hong Kong serious crime unit. The two begin with a rift over a cold case: three years earlier, To's sister was murdered and the killer escaped after Yim, then a police constable at the scene, did not shoot. When Yim is promoted into the Criminal Investigation Department and placed under To, he treats her with prejudice. During his investigation of his sister's case, To learns that the fugitive Yim had spared was not the real killer, and the two reconcile; their partnership deepens across successive cases until they together capture the true murderer.⁴

The eight adapted cases are named in promotion as the Caesarean baby-theft case (剖腹夺婴案), the doll-head corpse-hiding case (公仔头藏尸案), the rogue-policeman serial killings (魔警连环行凶案), the professor's killing of his wife (教授杀妻案), the human-meat siu mei case (人肉烧腊惨案), the kidnapped baby girl case (绑架女婴案), the online-luring murder case (网路诱骗杀人案), and the tycoon kidnap-and-murder case (富豪绑架撕票案). Because the real cases occurred in different years within the previous 15, the plot threads them together chronologically.² Each unit case has its own lead actors, including Tau Wan-yue (陶大宇) in the tycoon kidnap unit, Lillian Ho (何嘉莉) in the doll-head case, and Rebecca Zhu (朱晨丽) in the baby-theft case.²

Production approach

A reversed narrative. Chief producer Leung Ka-shu, managing director of Media Asia Television Production, said the series deliberately departs from the conventional Hong Kong police-procedural formula by devoting more screen time to the perpetrator's psychology and the process of the crime, with the police serving to connect clues rather than anchoring every scene. The intent, he said, was for viewers to understand how each case happened and feel a sense of familiarity with the settings.¹

The 12-episode length itself marks a break from traditional Hong Kong drama practice; a reviewer for 8world noted that the same material would previously have run to 30 or 40 episodes. The anthology structure also required more actors and more frequent location changes, and Leung described raising the production values in lighting, cinematography, and performance within a limited budget, with filming split between Hong Kong and mainland China to control costs.³^•¹

The cast drew comment for its density of veteran Hong Kong performers, most with TVB backgrounds; viewers described the show as having a strong TVB flavor. Miu returned to television drama after six years away and said he took the role because the real-case material read like a documentary.⁷

Reception

The series premiered on Youku on April 16, 2026, and on TVB Jade from May 4. Its TVB premiere week topped the Jade ratings chart at a highest cross-platform rating of 21.1 points, about 1.36 million viewers, ahead of the long-running news program Scoop; the finale week reached 21.7 points, about 1.4 million viewers, the series' highest figure.⁷^•⁸^•⁹ At the end of its run, Yunhe data assigned it an S rating.¹

Critical and audience responses diverged. A reviewer for 8world praised the fast pace suited to busy urban viewers but criticized the near-absence of suspense, since culprits are often revealed to the audience immediately, and found the psychological characterization of the cast thin; the same review noted that several units altered the original cases' culprit gender, number of perpetrators, and motives substantially.³ Youku's producers acknowledged viewer feedback that the detection process felt insufficiently satisfying, and said a potential second season could rebalance the proportion between perpetrator stories and police investigation.¹ IMDb listed a 6.9/10 rating from 18 votes.¹⁰

Producer Leung said the case-based format is extendable and that the team had already collected material for further development; Media Asia's production chief promised a second season at the drama's press event.¹^•¹¹
