Lynn and Sue are sisters whose father developed a cutting edge global surveillance tool before he and his wife were murdered for it. As a result of this the sisters became hired killers, with Lynn doing the killing and Sue guiding and advising remotely. When they complete a major job it leads to two events - firstly, their employer looks to silence them by killing them, and second, a driven cop, Hong, picks up their trail and begins to hunt them down.
As many of the audience for this film likely were, I was attracted to this film by the beautiful women on the dvd cover just as much as I was by the promise of martial arts action. The plot starts out as the standard thing with hired killers and `tough cops who are out to get them but also admire/relate to them', so nothing new there. Meanwhile the action is good but it will be standard fare for HK fans (in fact, for most of the world now thanks to Hollywood embracing it's style), although, having said that it is still entertaining even if I always find the very unnatural looking wire work to be a bit offputting.
The opening scene, where Lynn expertly moves through an office block to the strains of `why do birds etc' easily marks out the style of the film (not original, but fun) and the fights are good and have a good dramatic sense to them. The plot may well be seen elsewhere but it still has good touches and twists that will come as a surprise to many despite the familiarity of the plot basics. The cast are pretty good. The two lead actresses, Qi and Zhao, both play their roles with confidence and, needless to say, they are both very easy on the eye (and then some!). Mok is pretty but looks ugly next to these two - however she has a good character and has a fun, tough attitude. The support cast are evil bad guys and comedy sidekick cops, they all do what they are supposed to do, but to be honest the focus is always going to be the main women.
Overall, this film is not anything original or special but it is still quite good fun with plenty of stylish action. The plot has just enough going for it to carry it off, while the leads' good looks and appealing characters are a draw in themselves. Fans of the genre should enjoy it even if it doesn't stand out.
