A Seattle dock worker named Luk (Yuen Yat-chor) gains his US citizenship after seven years working illegally and plans to spend his new found freedom living a normal life with his ageing mother. Right from the off, Luk’s plans turn to dust after he witnesses a murder and then loses a videotape which could bring the culprits to justice. Hoards of gweilo fighters want their nasty mittens on the tape and soon enough the cops get involved. First there’s impulsive super kicker Donnie Yen and sentimental nutcracker Cynthia Khan, then there’s an intriguing subplot involving crooked cop Michael Wong who seems to be leading a crack racket involving the CIA and a celebrated bunch of high powered officials. With such a packed agenda it is surprising the film contains so much action, and all in a swift 90 minutes. At breakneck speed, then; witness Cynthia Khan smacking about some scumbag on the roof of a speeding car and falling from a bamboo scaffold, and Donnie Yen getting pummeled on a motorbike before beefing up to kick Michael Wood’s ass in a fully-charged smack-down finale. This is decent, edgy stuff with some brilliant fight scenes, and well worth hunting down.
