In the movie Gun Woman, wealthy Japanese businessman and politician named Hamazaki spent years covering up his son’s brutal rapes and murders. After the businessman’s death, his son received a large inheritance, but only if he left Japan. So naturally, Hamazaki’s son traveled the world, raping and murdering many women in many countries. One of his victims was the wife of a Japanese doctor, whom he believed was responsible for his father’s death. After killing the doctor’s wife, he turned himself in to the doctor, leaving him crippled.
As a result, the doctor decided to take revenge on Hamazaki’s son. A few years later, he was taken in by a drug dealer, a young woman named Mayumi. He does so in the hope of training her to become a “Sexy Assassin” who can approach Hamazaki’s son and kill him.
Stained with violence and lots of blood, Sexy Assassin also has many bold sex scenes, in other words, this is a true 18+ action movie, and also very Japanese, meaning that the entertainment factor is put first while the action scenes and acting are not the strong points.
