The Infernal Walker (2020) Timeline Explained – Every Event in Order

Ting was forced to torture Van because Van was a fellow undercover cop who had been captured by Shawn, the leader of the Fuk Wo triad. To maintain his cover as a ruthless triad member, Ting had to participate in Van's torture and execution. This brutal act demonstrated to the gang that Ting was fully committed to their cause, proving his loyalty and preserving his seven-year undercover identity.

Foreshadowing: The opening scenes establish Ting's precarious position, where any sign of weakness could expose his true identity.

Sung kills Sin-yeung and frames Ting because Ting's invisible marker had exposed the Ap Lei Pai operation, and Sung needed to eliminate anyone who could link him to the drug trade. By framing Ting for Sin-yeung's murder, Sung aimed to turn the Fuk Wo triad against Ting and remove a potential witness to his criminal operations. The frame job also served to protect his mole East and maintain control over both the criminal and police sides of his empire.

Foreshadowing: Earlier, East discovers Ting's invisible marker writings, which directly leads Sung to suspect Ting's true allegiance.

The Ap Lei Pai bust was a calculated setup orchestrated by Brother Hei and Sung. While Ting and the police believed they were raiding a real drug deal, the operation was actually a trap designed to expose any moles within Fuk Wo. The drugs and cash involved were counterfeit and low-quality. The real drug trade was simultaneously happening in Central, far from the police raid, allowing Sung to continue his operations while testing Ting's loyalty.

Foreshadowing: Hei selects Ting specifically for this operation, emphasizing it as a test of his trustworthiness to the triad.

Ting discards Tuen's police badge as a symbolic act representing the moral ambiguity of undercover work. Tuen, despite being a corrupt cop who worked for drug lord Sung, ultimately chose to kill Sung in the final confrontation, dying in the process. By throwing the badge into the water, Ting acknowledges that the line between cop and criminal has become indistinguishable, and that the undercover life has taken an irreversible toll on his own identity.

Foreshadowing: Throughout the film, Tuen's struggle between his criminal dealings and his genuine desire to become a 'real policeman' foreshadows this tragic resolution.

In the climactic showdown at the docks, Sung kicks Tuen into the water and turns to fight Ting. During the struggle, Tuen surfaces and shoots Sung. Sung fires back in return, killing Tuen. Simultaneously, the gunfire strikes Sung himself, resulting in both men dying from their wounds. This simultaneous death represents the ultimate consequence of their intertwined paths as criminal and corrupt law enforcer.

Foreshadowing: Tuen's earlier decision to help Ting expose Sung, despite their previous opposition, sets up this final act of vengeance.

Ting continues his undercover work despite being emotionally scarred by Van's murder because he is so close to achieving his goal of bringing down the Fuk Wo triad. After seven years of infiltration, leaving would mean all his sacrifice and moral compromise would be for nothing. His reluctant resolve to stay stems from a combination of duty, the sunk cost of his operation, and the need to see the mission through to expose the criminal network.

Foreshadowing: The narrative establishes early on that Ting has been eroding his moral boundaries for years, making it difficult to exit the undercover life.

During the scuffle, the hitman fatally injures Nasty before being subdued and captured by Ting. Nasty's death adds to the personal cost Ting pays throughout the investigation and motivates him to call Tuen for help in exposing Sung as the true mastermind.

Foreshadowing: Ting's hunt for the hitman intensifies after Sin-yeung's murder, with Nasty assisting throughout the investigation.

Tuen turns against Sung because Sung killed Sin-yeung, the woman Tuen loved. Although Tuen had been working for Sung as his mole within the police, the murder of Sin-yeung crosses a personal line that cannot be ignored. This betrayal drives Tuen to help Ting expose Sung, culminating in Tuen shooting Sung during the final confrontation at the docks, even though it costs Tuen his own life.

Foreshadowing: Tuen's relationship with Sin-yeung was built on his promise to become a legitimate policeman, making her death a direct betrayal of that dream.
