Jealousy, desire, trust, and revenge. A complicated love triangle emerges during an investigation into the theft of a woman's kidney. At a wedding party in a fancy hotel, a guest happens on the victim. The guest, Chi Ching, reports seeing a suspicious woman at the wedding, and at a police station, it's disclosed that the woman in question, Suen Ling, has slept with Ching's fiancé, Wei. He claims he loves only Ching, but Ling keeps showing up. Reassured by Wei, Ching tries to befriend Ling. Ling's back-story, Ching's health, and Wei's desires keep the love triangle spinning. It's not back-stabbing that Ching must worry about, but a 9-inch incision on her side. Written by <jhailey@hotmail.com>

A Taut Thriller
21 September 2008 | by crossbow0106See all my reviews

A tense psychological thriller with horror overtones, this film stars Lee Sinje as Ching, a successful woman with kidney problems and Karena Lam as Ling, a healthy lady who resents Ching because she is successful. Ching is dating Wai and, it turns out since they can't be intimate due to Ching's problem, Wai is cheating on her with Ling. If that was all there was to it, it would be enough, but the film is also about someone who cuts kidneys out of people so they can be sold on the black market. Ching thinks Ling is behind it. However, before Ching leans about Wai and Ling, she tries to befriend Ling, since both of them are kind of lonely. The pairing of Ms. Lee and Ms. Lam is superb. Any scene they are in together elevates the film. I think the fact that they became friends during the production (they both said so on the Making Of featurette on the DVD) makes their acting together much more natural and interesting. Ms. Lee has become a very good actress over time and she gets to stretch a bit, gasping in terror and surmising the goings on (or, think she has) admirably. Likewise, Ms. Lam is very good. The other carriers are minor, this is Sinje and Karena's film. I recommend it to anyone who likes tense thrillers. Since its about the cutting out of kidneys, it can get bloody, but its not really a horror film, so that makes it better. I'd like to see these two ladies reunite for another film. They work very well together. Watch this.
