An international gang of jewel thieves is hitting stores in Hong Kong and moving the merchandise through Japan and South Korea. An Interpol agent (blond, statuesque Evelyn Kraft) assembles three policewomen, one from Hong Kong, one from Tokyo, and one from Seoul to bring down the gang. The girls go undercover at a nightclub owned by the villains. The Hong Kong girl is to be the assistant to the knife thrower who performs at the club and who is the most deadly of the villains. This causes problems when her boyfriend (the son of one of the jewel store managers murdered by the gang) happens to show up at the club.
That is about it for plot. The rest of the film is set up for the action scenes. Another reviewer complained that Deadly Angels had slow stretches. This is true up to a point. As expected from the opening Shaw Brothers logo, Deadly Angels is clearly a 1970's kung-fu film rather than a 1980's action spectacular. The pacing reflects this. Firearms are used during the robbery scenes and the final assault on the villain's mansion (this latter treats the viewer to the image of Miss Kraft wielding a rocket launcher). The rest of the action consists of fighting. However, these are usually pretty good fight scenes. In fact, I thought the best action sequence was the Korean policewoman taking down the Seoul connection about twenty minutes or so before the climatic set piece.
How much entertainment one gets from Deadly Angels will depend on how much one likes to see pretty girls kicking butt. I liked the film. In fact, my only other complaint (aside from the slow bits) is that the reptile loving murderess does not have a fight scene.
