Hong Kong action film. There's a cop, he has a partner undercover in a Vietnamses gang. He gets rumbled and there's a bit of fighting to be had about it.
There are few fight sequences as good as the whole final scene. But leading up to that it could have done with having a little more going on (car chase and on foot chase a little underwhelming). Wasn't particularly sophisticated, but at least it brought up many issues: corrupt police, immigration/diaspora communities and over-zealous, violence-consumed police officers, but made no sincere effort to try and deal with any of them. Short film, good fun.
