Thriller: A Cruel Picture. 1973.
A young girl is sexually assaulted and becomes a mute, when she is offered a ride she is lead to a life of prostitution and seeks revenge on those who abused her.
This is pretty grim, but that's the way the audience love these revenge films, sadistic torture to vulnerable females can be upsetting to anyone but here Madeleine bides her time and decides to fight back. We see her being drugged and sold as a sex slave (yes there is some hardcore scenes and close up of everything in the uncut version which I just watched) but the more exciting scenes was her revenge.
The film is not fast paced so you will need to have the patience for the build up of some scenes, Christina Lindberg who plays the lead character does do a decent job in this that can certainly make your eye twitch at one specific scene.
