The two cops go undercover and... well you can guess the rest. Yes they both fall for two girls who work there. Andy falls in love with Chan Hui Ying... unfortunately she has a beefy ex-husband who wants to beat up anyone who touches his ex.
As guys who have been with Ying have ended up dead and Andy gets threatened with a knife by the ex he becomes the suspect for the murders. But then the ex is gunned down too. So who is it? The jealous barman who is secretly in love with Ying? Though you know Sarah Lee seems very close to her too...
The film is entertaining low-budget HK fun, the plot is fairly coherent (no weird tangents which is a rarity in HK movies of the period) and keeps you guessing for a time although an experienced HK movie watcher should be able to guess who the murderer is before the unveiling because the other suspects are just too obvious. There is even a showdown with explosions! It isn't that original but worth it.
