This is probably Sammo Hung's best work before embarking on his venture to start D&B films. All star cast graces this movie including Jackie Chan, and Yuen Biao. Other stars reads like who's who of Hong Kong movie industry of the '80s.
Five ex cons and a girl starts a cleaning service. They just try to make their living, but soon they get involved with local gangsters, by taking their brief case filled with counterfeit money. What results is a mayhem of trouble and actions relating to the six of them. They find themselves in all sorts of strange situations, and compromising positions, but they use their ingenuity to get the best of the gangsters.
It's hard to tell if this is a comedy or an action movie. Most of the actors are not action stars, but regular movie actors, so it's not like endless action scenes in Jackie Chan's movies. It's more like old school Hong Kong comedy with some good actions inserted in between the story. Some action scenes involving Jackie Chan is a classic, like the one he hangs on to a car wearing his roller skates during a chase.
This is one of the classics from the '80s, and is recommended for viewing.
