The best Hideo Murota’s thriller movies on Google Play Movies

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.

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.
