This had some sort of plot or something like that but I was too busy enjoying the action and comedy to give it much thought. Basically, this is 90 or so minutes of pure fun starring Jackie, Sammo, and Yuen Biao. What more could a HK movie fan ask for? Unlike many Jackie movies, there is no slowdown in the middle of the film for a lengthy (and often dull) plot exposition. The presence of Sammo and Yuen Biao really add a lot to the film, as these three work quite well together, especially in some wonderful comic moments between various combinations of the three. Yuen Biao's role as a slightly deranged mad scientist/kung fu fighter was particularly amusing. There's a rumor that these three might get together again for another film sometime in the future. One can only hope.
