The film is based on a true story and focuses on a female prison inmate who fights for women's rights while still in jail.

Coming as a complete surprise to her, she is convicted, receives the maximum sentence of 10 years and is sent to a women's prison, leaving behind her husband Larry and daughter Carey.

Sergeant Crang, determined to keep Lynn silent, watches her every move, prohibits her from receiving visits from her husband and even physically assaults her.

To collect proof, Lynn tries to convince fellow inmates to support her, but at first no one is willing to cooperate because they are either afraid of Crang or Angie, who forces the girls to remain silent.

Angie has always been profiting from the corrupt system, getting drugs from the police and being released on supervision once a week to prostitute herself.
