The Ladies Club (1985)

Los Angeles police officer Joan Taylor is gang-raped by a trio of burglars in her own home. When the three rapists get caught, go to trial, and get off through a legal technicality, Joan starts to go through women's support meetings where she forms an alliance with some other rape victims and a resident doctor, Constance Lewis, whose daughter was raped and killed by a sex offender. Joan takes charge of the group and leads them out to abduct and surgically castrate various men who have committed rape and gotten away with it. But the women's personal problems soon get in the way.
