Directed by former critic Chen Kuo-fu, Shuang Tong (Double Vision) is a Taiwanese effort at combining various aspects of the crime and horror genres with the excitement of martial arts. Led by detective Li Feng-po (Leon Dai), a group of detectives use physical violence to get a confession from a suspected criminal. Meanwhile, several murders are occuring--a business man is found drowned in his office; a politicians mistress Chiang Hui-hui) is burnt to death in her apartment, and an American clerk (Geo Gerstein) is eviscerated in his own church. Without a background in finding serial killers, the Taiwan authorties see fit to call the FBI. Agent Kevin Richter (David Morse) teams up with foreign affairs officer Huang Huo-tu (Tony Leung Kar-fai), and the pair sets off on a surreal trail which leads them through psychedelic fungus and a strange Taoist cult fun by former-businessmen. Eventually, Huang's (Leung Kar-fai) own inner demons are exposed and turned against him in a violent conclusion. ~ Tracie Cooper, Rovi
