A schoolgirl who only thinks of Karate as being about winning fights gets involved with a criminal gang of fighters. She has to be rescued and reformed by her sensei (teacher) who leads her back onto the straight and narrow.

This may not be an ambitious or profound piece of filmmaking but it is a great example of the genre. A film I don't mind rewatching. The actors (including the female lead Rina Takeda) genuinely know karate.
