This movie has a white male lead. It is a low budget B movie with “no name” type actors. The story involves some type of evil villain who takes captive some type of scientist or doctor to run some type of experiments on his private ranch, which I think is an island. The daughter of the scientist/doctor gets involved with the white Kung fu/karate dude in trying to rescue the captured man. The movie was around late 1970s or early 1980s I think. Basically an action/martial arts fighting type movie. Who can tell me the title of this movie?
