Tycoon Lin Tai's daughter, Lin Mengmeng, finds herself entangled in a shocking murder case where she is suspected of killing her father’s fiancée, Yang Dan. With her defense attorney, Zhou Li, and prosecutor Tong Tao navigating the twists and turns of justice, the courtroom becomes a battleground of revelations and deceptions.
At the start of the trial, Zhou Li draws out a confession from Yang Dan’s personal chauffeur, Sun Wei. Through careful questioning, she exposes him as the true murderer, claiming he acted after Lin Mengmeng had carelessly hit Yang Dan with her red Cayenne SUV and fled the scene. This seemingly straightforward narrative appeases both the court and media, reinforcing the idea that Sun Wei is indeed the killer. However, the situation takes a turn when Tong Tao, who has a personal vendetta against Lin Tai, begins to suspect that something is off. He discovers Sun Wei's terminal brain cancer diagnosis and theorizes that Lin Tai must have bribed him to confess while manipulating Zhou Li into leading the case astray.
As the hearings proceed, a new twist arises when Tong Tao receives an anonymous email claiming to contain video evidence of Yang Dan's murder. A download attempt just before a court session results in the video self-deleting, leaving the prosecution empty-handed. Nevertheless, Tong Tao cleverly requests a recess, feigning the need to assess this supposed new evidence before aggressively cross-examining Lin Tai. During this riveting exchange, Tong Tao hints at Yang Dan's infidelity, which strikes a nerve with Lin Tai. In a moment of rage, Lin Tai confesses he was present in the SUV at the time of the incident and further admits to having pushed Yang Dan, leading to her tragic death. This bombshell causes an uproar in the courtroom, resulting in Lin Tai's detention while Mengmeng is exonerated of all charges.
As the trial unfolds further, Zhou Li discloses intriguing details about how her team obtained the infamous video, received through an anonymous source. Analyzing the footage reveals inconsistencies in Sun Wei’s leg movements, which raises suspicions about the timing of the recording. Zhou Li takes a daring leap in her investigation, following clues that lead to a deserted factory in Su Province. There, she uncovers that the interior mirrors the location of Yang Dan’s murder, confirming her suspicions that Lin Tai staged the footage to shift blame away from Mengmeng.
Meanwhile, Tong Tao stumbles upon Lin Tai's cryptic confession in the court footage regarding not wanting to be convicted before the "Dragon Back Wall." Determined to uncover the meaning behind this mysterious reference, he visits Lin Tai's hometown, where an elderly villager recounts a local myth: a tale of a dragon king sacrificing himself to save his son. This poignant story unveils deeper themes of love and sacrifice, resonating with Tong Tao.
The gripping narrative concludes with a striking phone call from Mengmeng to Tong Tao, hinting that she may confess to her father’s machinations to safeguard her. The film leaves its audience pondering the lengths to which a father will go for his child and the complexities of love, loyalty, and sacrifice embedded within their familial bond. Through this engrossing legal drama, viewers are not only entertained but also prompted to reflect on the overarching power of fatherly love amidst adversity.
