Helga, la louve de Stilberg 1978

Vicious warden Helga runs the castle penitentiary Stilberg for female political prisoners with an iron fist. Stubborn and recalcitrant new inmate Elisabeth Vogel, who’s the daughter of a rebel leader, runs afoul of Helga after she finds herself incarcerated in Stilberg. Elisabeth eventually plots to escape from Stilberg in the wake of becoming fed up with being on the receiving end of Helga’s endless cruelty and perverse sexual desires.
