First off, "Angel's Mission" ("Born To Fight 2" in my country, apparently "Born To Fight 5" in others) has nothing to do with "Born To Fight 1", since the merging of separate films into a 6-part "series" is an invention of the cinema distributors at the time.
Anyway, we see Yukari Oshima as a Japanese police officer in Hong Kong on the trail of a girl trafficking ring. In doing so, she realizes that her mother (!) has a managerial role there. We are also watching a Gangster boss who hires a new member as his right-hand man, which insults the previous Number One and leads to his betrayal. Whatever the problems are, Yukari has many opportunities to punch or kick bad guys, and that's really just about it. A mediocre action movie.
