The best Hideo Murota’s thriller movies on Apple iTunes

After being cruelly set up by a crooked detective named Sugimi (Isao Natsuyagi), whom she loved, Nami Matsushima (aka Matsu the Scorpion) (Meiko Kaji) is sentenced to do hard time in a women's prison, which is run by sadistic and horny male guards. There are 700 other prisoners, making Matsu number 701. Her crime was making a failed attempt to stab Sugimi on the steps of the Tokyo Metropolitan Police Headquarters because he used her to win favor with the Yakuza. While in prison she meets inmates like Yuki Kida (Yayoi Watanabe) who was committed for fraud and theft, Otsuka (Akemi Negishi), jailed for burglary and extortion, and Katagiri (Rie Yokoyama) who has been impounded for arson and illegally disposing of a body.

Matsu, known to the prisoners as Scorpion, is locked away in the bowels of the prison as revenge for disrupting the smooth operation of the prison and for her disfiguring attack on the warden. Granted a one day reprieve due to the visit of a dignitary, she takes advantage and attacks the warden again. This leads to more brutal punishment and humiliation. But the punishment gives her an oppurtunity to escape along with six other female prisoners. Their surreal flight from prison pits the convicts against the guards, the warden and each other.

A look at the life of renegade yakuza, Rikio Ishikawa, particularly the years from 1946 to 1950 when his violent antics get him in trouble with his own clan, Kawada, and then with the clan of his protector, Kozaburo Imai. In these years, he can rely on Chieko, a young Tokyo courtesan who gives him shelter. He's banished to Osaka, where he picks up a drug habit. Through it all, he keeps his friends and enemies off balance with unpredictable behavior - and he seems indestructible.

After serving time, a defiant street thug is incensed to find his town overrun by two yakuza factions. He gathers his crew and takes them on.
