The story follows Cheung (played the hilariously named Emotion Cheung), a hard-working restaurateur, and Kuen (Faan Yeung), his wife and bane of his existence. When Kuen's attractive cousin Fung (Paulyn Sun) shows up, Cheung's life is thrown into a spin and he finds himself having a steamy affair. But Fung is not as sweet as she seems, as Cheung finds out when she murders his wife and feeds her hacked up corpse to his patrons as tasty barbecued meat. Lucky for Cheung, one of his regulars is an incompetent but good natured cop (Anthony Wong), who knows something is up.
Untold Story 2 has a fun cast. I assumed Anthony Wong's role would be nothing more than a cameo, but he gets a lot of screen time and appears to be having a blast in his goofy role. Sun is also excellent as the psychotic Fung. She's genuinely likeable before she flips, and genuinely disturbing once she does. But the real stand out is Cheung as... um... Cheung. There's a naturalism to his performance that really had me feeling for him.
If assessed only on its CAT III goodies, Untold Story 2 is somewhat lacking in its sex and violence quota. But its few moments of brutality are reasonably gruesome and well executed, especially in its electric-knife-wielding finale and a repulsive barbecued human eating montage. The best thing about Untold Story 2 is, unlike many of its contemporaries, it's watchable in its less offensive moments. Take my praise lightly though. This has got nothing on the unhinged original. But it's consistently entertaining with a few great moments." - Some Dude On The Internet
