Necrophobia (1995)

A young & happily married couple, Mark and Rebecca, are living in a remote countryside farm. When Rebecca dies in a disastrous road accident, Mark loses all his will to live and spends the next following days chain-smoking and visiting his late wife's grave at the cemetery. There, a ravishing woman approaches him and even invites him to a romantic dinner at her place. Unfortunately for Mark, the woman – Colette – has serious mental issues and she's completely subjected to the will of her deranged psychiatrist. Dr. Bernhardt's "therapy" causes Colette to dig up fresh cadavers; only to mutilate them and even have carnal intercourse with them!
