Gun Woman (2014)

This Japanese gem was much more entertaining than I was expected and I think it really deserves your attention if you are into the dark Asian thing you know. A doctor seeks for revenge from a crazy sadistic killer, responsible for his beloved wife's death. He finds a young female junkie and trains her to be the secret weapon for achieving his goal. The mission is really difficult as he has to pass her though an underground camp where strange people fulfill their sexual fetishes. The price of completing her task for this gun woman is to gain her freedom at last. Despite its low budget and maybe its amateur cinematography, especially in the beginning, this mixture of dark beauty and action will be remembered for some years, hopefully.
