Overheard (2009) Timeline Explained – Every Event in Order

Gene Yeung realized that the recording contained evidence of illegal stock manipulation by Feng Hua International. By deleting that specific portion, they could profit from the tip without leaving a record that would expose their own illegal trading. Yeung pressured Lam because deleting audio evidence was the only way to legally profit from the information they had gathered through their surveillance operation.

Leung knew that reporting the murder plot would expose their illegal stock trading activities, since they had been using privileged information gathered during the surveillance. Max Lam pleaded with Leung not to report it because doing so would ruin their careers and land them in prison. Leung weighed the risk and chose to intervene directly by ambushing the killer himself, hoping to stop the murder without involving the authorities.

Foreshadowing: Earlier, Leung had discovered Lam's unapproved trading and warned about the risks of exposure.

Leung had bribed Wah, one of the Boss's subordinates, using the $15 million in profits from their stock trading. In exchange for the money, Wah agreed to fake Leung's execution rather than actually kill him. This allowed Leung to disappear and work secretly as an informant, using Wah as his covert asset to gather evidence against the Boss.

Gene Yeung was the sole survivor of the Boss's ambush on the three officers and their families. The timeline shows that Yeung managed to escape the initial attack, though Max Lam was killed along with his family. Yeung later resurfaced a year later, working as the police driver who transported the Boss and ultimately drove him off the bridge into the harbor.

The manager's girlfriend had seen Leung's face during the ambush to prevent the manager's murder. She contacted the Boss's men, revealing which officers were involved in both the stock trading and interfering with their murder operation. The Boss ordered the killings of the officers and their families to eliminate witnesses and silence anyone who could expose his criminal network.

Foreshadowing: The manager's girlfriend glimpsed Leung's face during the ambush to save the manager.

The three officers liquidates their shares for approximately $15 million after the stock surge. Leung later used this entire amount to bribe Wah, the Boss's subordinate, in exchange for faking his execution and becoming Leung's covert asset to bring down the Boss. The money essentially became the tool that enabled Leung's revenge plan.

Gene Yeung, who survived the earlier ambush that killed his colleague Max Lam and Leung (temporarily), was selected as the police driver for the Boss's transport. Rather than let the Boss be taken into custody legally, Yeung used the opportunity to drive the Boss off an unfinished bridge into the harbor in a murder-suicide. This was his personal act of revenge for the deaths of his colleagues and their families.

During the ambush to prevent the Feng Hua manager's murder, Leung's face was briefly seen by the manager's girlfriend when she witnessed the confrontation. Days later, she spotted Leung at the station with Yeung and Lam, recognized him, and contacted the Boss's men with the tip that led to the trio being targeted.

Foreshadowing: Leung's face was seen by the manager's girlfriend during the ambush to prevent the manager's death.

Mandy Yam was Inspector Leung's romantic partner, and she happened to be the wife of Leung's friend Lee. After Leung faked his execution by bribing Wah, the story does not explicitly detail what happened to Mandy Yam. She presumably believed Leung was dead, as his death was staged to appear real.

The police needed sufficient evidence to build a case against the Boss, who was a powerful criminal figure operating through Feng Hua International. The surveillance unit was gathering evidence through intercepting communications, but the officers compromised their investigation by using the information for personal profit. Leung's plan involved using Wah as an insider to gather the concrete evidence needed for a conviction, which is why the Boss was only exposed a year later at the charity function.
