Trinity of Shadows

Passionate Detective Tze-Wei attempts to protect a sex worker who resists her help, as her precinct battles the City Councilor in a feud that dates back a generation.

Tze-Wei becomes consumed by a dark tragedy from her past after learning the identity of a recent homicide victim -- in a case with striking similarities to a murder that took place 23 years ago.

As he gears up for re-election, Chi-Hsiao is hit with an assassination attempt. While Tze-Wei believes it may have been a warning shot, the shooter has a bigger agenda.

Tze-Wei is assigned to Chi-Hsiao's security detail, Chia-Hao clashes with his boss, and Ching-Yao discovers a body while hosting his friends from Hong Kong.

When the body in the suitcase is identified, the team is rocked by the case's similarity to a murder Tze-Wei's father confessed to 23 years earlier -- and the copycat murder of Chia-Hao's girlfriend three years ago.

Tze-Wei, Chi-Hsiao and Chia-Hao team up off-the-clock to pursue a forbidden suspect. But they're in for a surprise when confronted by an even more dangerous criminal.

After his attempts to expose Ming-Chieh's connection to the murder victims are quashed, Chia-Hao goes rogue. Meanwhile, Chi-Hsiao and Tze-Wei grow closer as they become each other's only allies.

After surviving an encounter with an armed Ta-Dong, Tze-Wei and Chi-Hsiao try to reason with Chia-Hao, who realizes that his number one suspect isn't panning out -- but he's in too deep to turn back.

Chia-Hao continues to press both Ming-Chieh and Ta-Dong for details about Chien-Chien's death, before helping Tze-Wei solve one mystery -- while simultaneously unraveling another.

After Jia-Jia's sister shows up, Tze-Wei and Chi-Hsiao reveal details of their pasts, fueling a shared agenda in the present. Then, a nice day of sight-seeing with Ching-Yao and his girlfriend turns sour when Tze-Wei is abducted.

After escaping her captor, Tze-Wei finds herself falsely accused of a murder. Chi-Hsiao's attempts to help are thwarted by a rash of problematic rumors.

Tze-Wei tries to protect Chi-Hsiao from trouble, as Ta-Dong continues to mastermind everyone around her.

After Susanna gives Tze-Wei her mother's address, Chi-Hsiao encourages her to reach out while she still can, before they both learn new information from unexpected sources about the incident 23 years ago.

Tze-Wei and Chi-Hsiao go on an unusual field trip to confront ghosts of the past, while Ta-Dong manipulates Tze-Wei -- and everyone she loves.

Tze-Wei learns the shocking truth behind that fateful night, before an ill-timed reunion finally unearths 23 years of tension and an explosive conflict breaks out between her, Chi-Hsiao and Ta-Dong.
