There is a kind of plot, something involving an evil gangster mastermind (who has a rotating desk, excellent!) creating explosives and drug smuggling in his (evil) underground lair but the plot is just a bare frame on which to hang a sequence of excellent fighting set pieces.
The result is undeniably cheesy, fairly confusing but also highly entertaining. It is a 70s period piece and perhaps nothing that original from the time but worth seeing all the same. How many HK kung-fu movies had an ex-James Bond in them after all?
