The Untold Story 2

The story begins in 1978 in a small Hong Kong apartment where Chan Chi-Leung brutally beats and then burns a gambler named Keung to death for refusing to lend him money. To avoid police detection, Chan flees Hong Kong by burning his identification documents and changing his name to Wong Chi Hang.

Wong Chi Hang is shown working at the Eight Immortals Restaurant in Macau. He receives and tears up a letter intended for Cheng Lam, the restaurant's former owner, indicating unresolved issues related to the restaurant's ownership.

A family discovers a bag of rotten limbs washed up on the beach. Police officers Bull, Robert, King Kong, and Bo arrive to investigate, with their supervisor Inspector Lee joining them to examine the evidence, including identifying the limbs as belonging to Cheng Lam's mother-in-law.

Wong attempts to take over the restaurant, claiming Cheng Lam sold it to him, but is unable to do so officially without Cheng Lam’s signature. He later cheats at Mahjong and is confronted for his dishonesty.

Wong is caught cheating at Mahjong and reacts violently, stabbing a waiter in the eye, beating him to death with a soup spoon, and dismembering the body to make pork buns, disposing of the remains in a dumpster. His brutality indicates a series of escalating crimes.

Inspector Lee suspects Wong after questioning him at the restaurant. Surveillance is ordered, and Wong is caught attempting to dispose of evidence linking him to Cheng Lam’s family and is detained while trying to cross into China.

Inspector Lee uncovers that Wong murdered Cheng Lam and his family, stealing the restaurant. Wong denies the crimes and is tortured by police to force a confession, eventually breaking under pressure.

Wong is imprisoned and attacked savagely by Cheng Lam's younger brother Poon and his gang. To escape, Wong attempts suicide in the hospital after slashing his wrist and biting himself, leading to medical intervention.

Hong Kong police detectives reveal Wong’s true identity as Chan Chi Leung, linking him to the murder of Keung. They propose extradition plans, but Lee refuses and seeks to build a case against Wong in Macau.

Wong escapes from the hospital by taking a nurse hostage and overpowers King Kong but is quickly stopped by police. Authorities continue to interrogate him, using torture to obtain his confession.

After days of brutal torture, Wong confesses to a series of horrific murders, including Cheng Lam's family and others. He admits to killing them after a debt dispute, dismembering their bodies, and turning parts into pork buns.

Following his confession, Wong is returned to prison, where he has a final confrontation with police. He ultimately commits suicide by slashing his wrists, leaving the case unresolved as he dies before charges are filed.
