Trinity of Shadows

Detective Tze Wei is handling an assault case. When the police arrive at the scene, the victim Nicole decides not to press charges against the perpetrator, stunning Tze Wei.

Ordered to do administrative work, Tze-Wei receives an unexpected call for backup from a rookie police officer, Chia-Hao, who is investigating the case of absconded migrant workers. Disregarding protocol, Tze-Wei rushes to Chia-Hao’s aid.

City Councilor Yang Chi Hsiao is shot in his electoral district. Tze Wei rushes to the scene immediately and makes an unexpected discovery.

Tze-Wei takes on the task to safeguard Chi-Hsiao and identifies the shooter as a wanted criminal. Meanwhile, Nicole’s neighbour, Ching-Yao, discovers a body while hosting his friends.

The body is identified as Jia-Jia, a young woman linked to Chi-Hsiao. While Tze-Wei and Chia-Hao suspect a police cover-up, Chi-Hsiao is already one step ahead of them.

Tze-Wei and Chia-Hao decide to work with Chi-Hsiao to investigate Ming-Chieh. When he is released due to a lack of evidence, Chia-Hao is infuriated, as his grudge is driven by personal reasons.

Tze-Wei and Chi-Hsiao continue to investigate Jia-Jia's murder. They receive a critical tip by chance. Meanwhile, Chia-Hao continues to look into Ming-Chieh on his own.

Tze-Wei believes that Chia-Hao’s disappearance is connected to Ming-Chieh’s kidnapping. Acting ahead of the other police officers, Tze-Wei tries to get ahold of Chia-Hao but to no avail.
