This 2001 crime caper pits a persistent cop (charismatic baby face Lau Ching-wan) against an elusive high-stakes blackmailer (Ekin Cheng). The plot has more holes than a bullet-ridden vest, but that's hardly a concern for codirectors Johnnie To and Law Wing-cheong, who invest more thought in devising stylish, implausible chase sequences—across the roofs of office towers on foot, through Hong Kong's skyscraper canyons by car, and through crowded market streets on bicycles. Lau is always one step behind Cheng, a taunting, enigmatic Robin Hood figure with magic tricks up his sleeve. With Kelly Lin. In Cantonese with subtitles. 96 min.
