A Murder Erased

International narcotics officer CHOI (Eddie CHEUNG), has been demoted by his superior officer MA (Simon YAM) to local duties after partaking in bribery in the line of work. He’s assigned to a death scene investigation by YAN (Maggie SHIU) where the deceased, YUNG’s, body had laid undiscovered for eight years, and only recently discovered by maintenance workers during the renovation of an old block of flat. CHOI looks into CHIU (Timmy HUNG) as the prime suspect, and linking it to adultery with YUNG’s widow PING (Dada Chan) as an accomplice. The case soon comes under scrutiny by a high-ranking court prosecutor SANTO’S (Joe Junior). Under his inquiries, the investigator becomes the investigated, and CHOI’s actions fall under suspicion as all manner of inconsistencies come to light from his statement. YUNG was a man of many vices, with few crimes left untouched by his hand - rape, drug smuggling, blackmail and working alongside notorious gangster FAI WAI (LAM Suet). Has CHOI framed a pair of innocents? How did this case end up becoming an unsolved one? Who was responsible for burying this case?
