I saw this film on cable in a hotel room while I was in Taiwan. It had subtitles in both Traditional Chinese and English. The ads for this film made it look like it was going to be a horror film in the Japanese style that is so popular nowadays. It turned out to be a stylish and slick thriller instead. The production values were quite high, and the plot was interesting enough to keep one's attention. Basically, the plot has been expanded from the common urban myth about waking up in a bathtub full of ice cubes, with one's kidney removed. (Well, I hope it's an urban myth!) I would certainly recommend this film. Well acted and entertaining.
