Two martial arts experts are hired by gangsters to retrieve a precious item that they covet. Namely, a valuable necklace which has been split into two parts but which will reveal a Swiss Bank Account number when brought together. Different people have the different parts and with two separate teams in pursuit, needless to say, this leads to quite a lot of incident.
City Ninja is an example of the kind of low budget action movies being churned out in Hong Kong by the mid 80's. Its cheapness means this is pretty basic stuff in a lot of ways. As is mostly the way with these types of movies, the story-line is strictly by-the-numbers stuff which only really is there as a means of getting from A to B with as much martial arts action as is possible. As such, it's not especially distinctive or memorable from others in its category but will no doubt satisfy fans of this sub-genre nevertheless. I personally thought it was marginally better than average for this type of flick. The fighting scenes were pretty well executed and fairly convincing, while the odd downbeat ending appealed to me on account of its unpredictable strangeness.
