The summary tells it all. A woman is attacked by a recently released from jail rapist. While fighting him she managed to kill him in an access of rage. After hearing news of other released convicts attacking again and again she decides to stalk others and kills the one that attacks women. It's pretty much exactly what you would expect. Apart from the satisfying revenge part, there are some nice bits. Like her holding a plastic mask in front of the victims' faces to protect them from the blood spraying from the aggressor's throat. Or the woman that could have sold her to the police giving her supplies on the house.
