A young and mute girl named Madeleine, who lost her ability to speak after a traumatic childhood incident, lives a quiet life on her family's farm. Her sheltered existence crumbles when she misses her bus to town and accepts a ride from a seemingly friendly stranger. Tragically, the man drugs and abducts her, dragging Madeleine into the dark underworld of crime. She is forced into heroin addiction and coerced into working as a prostitute in order to repay an invented debt for her 'purchase' and accommodation, with any attempts to escape brutally punished.

Struggling with the harsh realities of her enslavement, Madeleine is subjected to terrible abuses that fuel her desire for vengeance. As her life spirals further into despair, Madeleine's desperation leads her to take lethal training in self-defense, firearms, and driving. All the while, she meticulously plots to retaliate against those who have wronged her, including the man responsible for her captivity. With each passing day, her plans for revenge become more elaborate as she transforms from victim to avenger.
