For those of you who are familiar with the Female Prisoner Scorpion movies, this movie is NOTHING like those.
Female Prisoner Sigma is a B Pink movie. The plots is minimal. Basically a girl going into prison to investigate and avenge her sister's mysterious death.
All the women in prison staple are in the movie, sadistic warden, sadistic female guard, turn coat prisoner and some nudity. The only things missing were the shower scenes and the lesbian scenes.
The plot is simplistic and the acting too. However it is not that bad of a movie. Take it for what it is a B Pink prison movie that is shot on the cheap, cheap effects, cheap sets and probably cheap actors. A good way to waste an hour.
