I saw this on cable TV in Australia and I actually quite enjoyed it. I tended to think it was slightly tongue in cheek. The cop (Craig Fairbrass) arranges for this hit woman to kill someone for him, but just in case he gets found out, he hires a bunch of amateurs to make a hit on the hit woman. Hilarity doesn't quite ensue, but it was very watchable, although mainly for 11pm on a weeknight when you've got a day off the next day. Worth seeing but don't go out of your way.
