Wife to Be Sacrificed (1974)

A wife charges her husband with sexual battery. He escapes from the police and goes into hiding. In three years, she divorces him and tries to put the pieces of her life back in order, when suddenly he returns. Obsessed with rage and hatred, he kidnaps her and brings her to a house in a remote wooded area. There he disciplines her vehemently, subjecting her to increasingly shocking forms of sexual torture, tetherings, suspensions and humiliations. Astonishingly, through the rage and lust, the pair develops a relationship that pushes the boundaries of lurid passions and perverse obsessions.
