The serial suspense drama “The Truth Within” (Bo Jian) has confirmed its broadcast schedule. On December 26, the production team officially announced that the series will premiere December 29, streaming exclusively on Youku Video and Migu Video.
Directed by Chen Kuan Chung and David Chuang, the drama stars Luo Yunxi, Cya Liu, and Jiang Qi Lin in leading roles. The cast also includes a special appearance by Fei Qi Ming, an invited appearance by Liu Huan, and another special appearance by Zhao Zi Qi, with supporting roles played by Liu Tian Zuo, Li Jia Hao, and Wang Qian Guo.
A Forensic-Driven Mystery Narrative
Set within the Licheng Criminal Investigation Detachment, the series centers on Qi Sizhe (Luo Yunxi), the head of the forensic department. His motivation is personal. He’s determined to uncover the truth behind the mysterious car accident that killed his girlfriend, Yu Fei.
Working alongside Vice Captain Zhu Qingyue (Cya Liu) and Captain Han Feng (Jiang Qi Lin), Qi Sizhe becomes entangled in a string of bizarre unsolved cases. As investigations deepen, an old drug trafficking case—known as “Raw Diamond”—resurfaces, gradually exposing links to every crime and to Yu Fei’s death.
Six Cases, One Core Mystery
The newly released trailer reveals six major cases driving the plot: “The Lolita Homicide,” “The Funnel-Web Killer,” “The Human Jigsaw,” “The Fatal Policy,” “The Vanishing Portrait,” and “Original Sin.” Each case stands on its own, yet all feed into a larger criminal structure.
“Do you know there is a type of person who fantasizes that they are a spider?”
This line, delivered during Qi Sizhe’s forensic analysis, underscores the show’s psychological angle. Fast-paced edits follow—nightclub violence, bodies trapped in webs, skeletal formations, and blood-stained drawings. The imagery is direct and unsettling, reinforcing the drama’s suspense tone.

A Web of Clues and Characters
In the “The Truth Within” poster, Luo Yunxi, Cya Liu, and Jiang Qi Lin stand at the center of a massive spiderweb. Scattered across it are torn photos, evidence tags, and symbols tied to all six cases. The visual reinforces the show’s structure—separate crimes, one inevitable conclusion.

As the investigation closes in on the truth, the identity of the mastermind behind the Raw Diamond drug ring shocks Qi Sizhe. The culprit, it turns out, has always been close.
“I will definitely put a period on this case,”
The statement signals both resolve and an approaching confrontation between justice and corruption.
Production Quality and Genre Focus
Marketed as a forensic-led suspense series, The Truth Within emphasizes professional realism. The production was guided throughout by forensic experts, ensuring accuracy in procedures, lab settings, and investigative logic. From cave-set spiderweb visuals to detailed police laboratories, the trailer highlights film-level cinematography and controlled lighting.
The drama also weaves in broader themes—psychological health, family dynamics, and anti-fraud awareness—without disrupting its crime-driven pacing.
With its case-within-a-case structure, experienced directing team, and strong cast lineup, “The Truth Within” positions itself as a major entry in the Chinese suspense drama lineup for late December.
