Popular HK rock group the Wynners play themselves in this Golden Harvest production. They plan to go to America to play a gig. The local druglord decides he wants to use the opportunity to smuggle some heroin, so he switches their instruments with ones filled with drugs. Unfortunately the Wynners have to cancel their gig, so now the druglord has to get back the laced instruments, creating a cat and mouse game with the boss's thugs, police and the Wynners themselves. This movie is only so-so and doesn't have much energy--action or comedy-wise. It's filmed straightforward and is kind of corny. But it's cool to see these future stars in their Wynners days with the groovy stage outfits, plus the catchy songs. Actually the best part of the movie is the opening sequence where they sing the title song (in English) and point up the credits. And it is kind of funny they show each band member with their own quirks and hobbies, Ah Lun likes soccer, another likes animals, Ah Yau likes sleeping etc. For a more entertaining film with the Wynners, see their third film "Making It."
