Johnny To and Ching Siu-tung co-directed this futuristic sequel to Heroic Trio set several years after a nuclear meltdown has contaminated the water supply with deadly radiation (a reference to the controversy over China's rather haphazard construction of the Dai Ah Bay plant near Hong Kong). Tung (Anita Mui) has settled down to raise her young daughter, Number 3 (Michelle Yeoh) delivers medical supplies, and Number 7 (Maggie Cheung) hijacks trucks carrying clean water and sells it on the black market. An insane mutant named Kim (Anthony Wong) controls most of the clean water, and teams up with a power-hungry colonel (Paul Chun) to stage a military coup. Tung is thrown in jail, and Number 3 works to free her while Number 7 teams up with a handsome soldier (Lau Ching-wan) to find a new source of water and liberate the region from the crazed despots. Damian Lau co-stars with Takeshi Kaneshiro and Kwan San. ~ Robert Firsching, Rovi
