The Untold Story is part of a sub-genre called Category III (abbreviated: CAT III), CAT III is a certificate given by the Hong Kong film censors to films that features extreme violence or excessive sexual content. The most notorious CAT III movies, are the ones made in Hong Kong. The Untold Story is based on an actual murder case that happened in Macau. Plot: Severed body parts are found at the Macau Bay, the police investigates and all the evidences leave to the "Eight Immortal restaurant", the cops suspects of Wong-Chi Hang, a man who escaped from Hong Kong after committing a gambling-related murder. The violence is taboo-breaking and bloody, the special effects are good, but i can't tell you how they are realistically shocking. The most sadistic scene is probably the one where Chi-Hang rapes and murders a woman, by shoving some chopsticks up her lower parts.... This movie features a excellent performance by Anthony Wong, as Wong Chi-Hang the serial killer, Anthony even won a best actor award for this movie (100% deserved !). Recommended for CAT III beginners or for who is tired of the same Hollywood "shocking movies".
