Sister Street Fighter (1974)

Translated from the original Japanese, the title would really be "Lady Killing Fist". The title Sister Street Fighter is just to cash in on the successful Sonny Chiba film The Street Fighter and is not a sequel or connected in any way.

Our heroine (Etsuko Shihomi) travels to Japan to find out what happened to her brother who seems to be missing. He was investigating a drug kingpin at the time of his disappearance. She eventually teams up with Chiba through the Karate school where her brother was training, and together they battle the drug lord who has an army of Martial Arts specialists.
