Moon Lee and Gam Chi-Gei portray Ellen Lee and Grace Chin, two officers who work for the C.I.D. These two are more than just partners though, they're roommates and best friends who graduated from the academy together; yet they still have a tendency to act like a couple of rookies. But one day, their sexist superior Commander Wong (Melvin Wong) has an assignment for them to do: it seems there has been a rash of murders involving young Chinese hostesses in the area. The girls all had the same thing in common, they were young and beautiful, worked in high-class clubs where there was a lot of money and sleaze, and after a couple of days of work they'd disappear and weren't found until a couple of days later. The M.O. of the killer is terrifying: he binds the women, beats and tortures them, and then rapes and kills them (sometimes, doing the last two parts, vice versa). As Grace sarcastically puts it 'this killer is a real sweetheart'.

So that's where Ellen and Grace come in, their task is to go undercover and find the identity of this loon and bring him in. At first the girls aren't interested in playing bait for a bunch of sleazy rich guys, but then Grace discovers something much more interesting: it seems that the owner of the nightclub is Brother Bill (super kicker Chui Jing Yat) who has gotten on the bad side of some dangerous people after screwing them over on an arms deal by killing the businessmen. Now, he wants to be 'top dog' of the underworld, but he needs to remove any obstacles that may threaten this move and so that's where the lovely Yukari Oshima comes in. She plays a free-lance killer named Yamamoto who uses a blowgun and other hand-made weapons to deal with her targets, but there's a chance our lovely assassin may not really be who she says she is...

That's the plot in a nutshell and here are some of the saving graces for the film:

• Good fights scenes, but at least one at the beginning had a little undercranking.
• The bonding between Ellen and Grace...these two are like sisters and they fight and behave like they were really family.
• There are some comical moments that make up for the lack of action at times.

• The movie had two plots, but didn't know which one to focus on so it was kind of confusing as to what direction the director wanted to take, but he tries hard to stay focused on one scenario at a time.
• Billy Chow is introduced into the story, but he's not given much screen-time. Even when it's time for him to display his skills, they do it too late.
• The fight scenes should've been filmed in the daytime...for some reason at night, there wasn't enough lighting to see what was going on.

I'll admit, "Beauty Investigator" had its moments where I was excited to watch it, but other times it would put me to sleep. But I still enjoyed it because it was a girls-with-guns movie and it had two of my favorite leading ladies in it--they had much potential but weren't really given much to work with. But the good thing is, they tried and made the most of it, and that's sayin something for a low-budget film like this.

Give it a shot if you're a Moon Lee or Yukari Oshima fan.
