I am trying to get the title of a movie I watched in early-mid 80s (1983?-1986?). Here's what I remember about the plot.
A small Japanese girl becomes a witness to her father murder in NY. I believe that her father was hired by NYPD as a martial arts guru, since NYPD decided to teach their stuff Karate or something of that sort. So, a rivaling group kills the father to get the lucrative assignment. The girl survives, grows up, becomes a very pretty young woman, goes to Japan and learns Karate and other fighting techniques. She starts her revenge, finding her father’s killers one by one and killing them. There is also something about a Martial Arts Festival (or championship), going on at that time and she is going there to find one of the killers.
Please help me get to this movie! Thank you in advance.
