The Prosecutor 2025

Police detective Fok Chi-ho leads his team in the pursuit of an armed robbery gang. Although they capture all the gang members, the leader leaves no trace linking him to the crime and is released without conviction. This incident causes Fok to lose faith in policing, prompting him to leave the force and study law.

Seven years later, Fok joins the Department of Justice and becomes a public prosecutor. Under the mentorship of pupil master Bao, he receives his first case involving drug smuggling. The defendant, Ma, receives a parcel from Brazil containing a kilogram of cocaine. Ma insists he is innocent, claiming he has only borrowed his address to a friend, Chan, who promises him money to alleviate his family’s debts. However, Ma’s defense lawyer, Li, and legal executive, Au, mislead him into believing he is likely to be convicted, urging him to plead guilty for a reduced sentence, which Ma and his grandfather, Uncle Ma, agree to. When Li approaches Fok to discuss the plea bargain, Fok finds it suspicious that the terms require Ma to take full responsibility while Chan is completely absolved. Nevertheless, chief prosecutor Yeung accepts the terms, believing they provide the best chance for a conviction. During detention, Ma learns from fellow inmates that Li has deceived him, causing him to reconsider his guilty plea out of fear of not seeing his grandfather again. Fok, who believes in Ma’s innocence, allows him to change his plea, which dissatisfies Yeung. In the first trial, Au and Li serve as prosecution witnesses. Despite Ma’s lawyer attempting to prove that they have misled him during negotiations, his claims lack evidence and are easily dismissed. Fok begins to defend Ma and question his own witnesses. The judge attempts to stop Fok, leading to a clash where Fok argues that the prosecution should focus on those who are truly guilty rather than simply securing a conviction. This argument damages Ma’s reputation with the jury, resulting in Chan being acquitted while Ma is convicted of drug smuggling and sentenced to 27 years for showing no remorse.

Realizing his mistake, Fok seeks to help Uncle Ma, who initially rejects him until Fok saves him during an assassination attempt. Uncle Ma reveals to Fok that they hired Li based on a recommendation from Lau, the owner of the restaurant where Ma works. After learning about the assassination attempt, Bao agrees to help Fok investigate, leading them to discover that Yeung has been the prosecutor in every case involving Au. Bao infiltrates a nightclub owned by Lau and overhears a conversation revealing that Lau and Chan are half-brothers. They learn that one brother solicits people to lend their addresses for drug smuggling, while the other pretends to offer pro bono legal assistance through Li and Au, who actually have them take the blame. Fok assists Uncle Ma in applying for an appeal, but Ma is later assassinated in a cha chaan teng. With the half-brothers as the only lead, Fok approaches other victims and eventually locates a girl willing to testify against Lau. Knowing Lau is exposed, Au attempts to persuade him to turn himself in and take full responsibility. However, he is murdered by Sang and Tung, Au’s drug lord associates. Meanwhile, Fok confronts Yeung, discovering Yeung’s innocence, and the two sets their differences aside.

During the retrial, Yeung serves as the prosecutor and buys time for Fok, who seeks to locate the hiding Chan. With the help of Inspector Lee, Fok’s former protégé, they find and convince Chan to testify. However, they are attacked on their way to court, resulting in Lee being severely injured. Fok and Chan continue to the courthouse by MTR, encountering Sang’s assassins during the ride. Fok dispatches them all and manages to reach the courthouse, where Chan delivers his testimony against Au. Ultimately, Ma is acquitted, while Au and his syndicate receive appropriate sentences.
