The Antichrist (1974)

Ippolita is a paralyzed young woman with serious mental problems stemming from the death of her mother. Her crisis of faith and the intervention of a well-meaning psychologist lead Ippolita to remember her past life as a witch during the Inquisition. Eventually, Ippolita becomes possessed and starts seducing local men, only to kill them. An exorcism seems to be the only solution to stop the madness.
