This bizarre action film/existential drama is like Wong Kar-Wai gone bad. Jade Leung stars as a rookie cop who witnessed her boyfriend/superior officer's death. She goes undercover but quits the force, and proceeds to wander around HK regretting her past. Her tortured soul finds a soulmate in the shady James Pax, who's regrettably a thief and a vicious killer. Even more, he may have been the guy who snuffed her late boyfriend, which is a plot detail of no real surprise.

Though the film posseses a typical genre plot, director Mak Tai-Kit leans heavily on Wong Kar-Wai's storytelling techniques to engage the audience. This means rampant voice-over and many arty sequences which only serve to confuse the audience. The filmmaking eventually rights itself for some normally shot sequences, but the damage has been done. The "artistic" atmosphere lends the film an uneasy pretension that only serves to alienate. Enemy Shadow is occasionally interesting, but ultimately empty and gratuitous. (Kozo 1995)
