A bunch of prostitutes go to a fancy party. Among them is Cat and a friend of hers. Among the guests is an American ambassador. The palatial house is owned by a mean guy named Carver. When the ambassador gets rough and kills one of the girls, all hell breaks lose. Carver decides to kill all the girls. Cat manages to escape.
Next morning while on the run she makes a phone call at a restaurant owned by Anthony. She steals his car and his friend's phone. Around this time the friend, named Julian, proposes they start a private detective business. Anthony eventually agrees. They get an "office" in a porn theater, hire a guy missing 3 limbs as an assistant, and take on the "case" of finding Cat.
Also looking for her is Carver. As it turns out Cat stole a hard drive of his with evidence of all sorts of wrongdoings. He hires a hitwoman Helen, a prim and proper English woman. And she's mean. She and the two morons follow the same trail--Cat's family in Spain, her pimp, and eventually the two find Cat just as Helen finds them all. They barely manage to escape. When Helen fails to do her job, Carver sends a hit-man after her. That causes Helen to join forces with the other 3, who now go after the ambassador and Carver. They crash another one of his parties and violence and the resolution ensues.
This movie is not at all what it seems like. Cat is a very secondary character, and no, she isn't not some action chick. Initially it's all about the two fools chasing after Cat. And they make terrible lead characters. Since they are so weak, the appearance of Helen livens things up considerably, except that she it detestable. Things improve when the Scottish hit-man appears but unfortunately he's there only for a short time. While the characters are lame, the story is alright and the action is pretty good. This movie delights in some of the extremes it shows. The settings in Serbia are pretty neat and interesting. Overall a fairly decent movie that's at times annoying but overall entertaining and action packed.
