Anonymous Signal (Chinese: 奪命提示; lit. 'Fatal Warning') is a Hong Kong police procedural television series produced by TVB, with Jazz Boon serving as the series' producer. It premiered on 17 March 2025 and ran for 30 episodes until 25 April 2025. Set against the backdrop of police investigations, the series blends action, suspense, and occasional comedic elements, and stars Joel Chan, Moon Lau, Owen Cheung, and Tiffany Lau.

Plot

The series follows Chief Inspector Keung Hey-man (Moon Lau) of the Criminal Intelligence Bureau (CIB), who receives a cryptic message from an artificial intelligence assistant known as Julie that leads her to a dismembered body. The discovery is soon linked to an ongoing serial murder investigation led by Inspector Kwok Bak-fei (Joel Chan) of the Major Crimes Unit. In response, senior officials merge the two teams to form the Anonymous Signal Intelligence Bureau (ASIB), a new unit tasked with handling cases associated with Julie’s unexplained signals.

As the investigation progresses, Julie’s messages appear to predict future crimes but often misdirect or manipulate the unit. ASIB becomes involved in a range of cases, including the “Limb-Sawing Maniac” murders, incidents of spontaneous human combustion, desiccated remains found in abandoned buildings, and disappearances connected to a clandestine orphanage. Throughout these investigations, Hey-man and Bak-fei grapple with the unresolved consequences of a failed operation three years earlier, which resulted in the death of their mentor, the breakdown of their partnership, and lingering psychological strain.

Parallel to the main investigation, undercover officer Wan Ka-lei (Tiffany Lau) renews her complex relationship with Chiu Chun-long (Owen Cheung). The two care for their adopted daughter, Tsz-yu (Lesley Chung), a young girl battling leukemia, whose well-being becomes an emotional anchor for both characters. As ASIB examines the origins of Julie, suspicions of an internal mole arise, heightening tensions and undermining trust within the team.

The investigation ultimately identifies Lee Kin-wo (Brian Tse) as the architect behind Julie. Working with corrupt police insider Kwan Chun-yu (Cheung Kwok-keung) and hired assassin Ling Lit (Bob Cheung), Kin-wo uses Julie to orchestrate a series of coordinated crimes, manipulating both law enforcement and criminal groups.

In the concluding episodes, ASIB uncovers Kin-wo’s full plan, leading to a confrontation in an “ultimate game arena.” During the encounter, Lau Lik (Jazz Lam) is killed while protecting his colleagues, and Kin-wo is killed by Bak-fei in hand-to-hand combat. Although the network controlling Julie is dismantled, the series ends with the activation of a new system, Julie 2.0, implying that the underlying threat persists.
