inspector mina kao (joyce godenzi), has just married into the wong family, by taking inspector bo wong (tony leung ka-fai) as her husband. bo's sisters (sandra ng, angile leung, sarah lee), in particular ling (carina lau), fell that bo is making a mistake by marrying the young, ambitious officer, who looks as if she'll be his superior sooner, rather than later.

still, mama wong (tang pik-wan) and her godson (sammo hung) manage to keep things together, until they get involved in the robbery of a nightclub. the robbery is prevented, but many people are killed as a result of ling blowing their cover. it is only when the vietnamese gang, who carried out the robbery, decide to take revenge against one of the gang who was killed by mina, that the wong sisters and mina start to pull together...

this is a pretty typical corey yuen film; touches of humour, touches of melodrama, a slightly clunky narrative and some solid action sequences, mixing gunplay and martial arts with style. godenzi and lau provide, along with yuen wah (the head of the vietnamese gang), take the lead in the bulk of the action sequences and do well.

good stuff.
