THE FORBIDDEN PHOTOS OF A LADY ABOVE SUSPICION

Minou is married to apparently wealthy businessman Peter. Peter is secretive and frequently absent from home, distracted by financial problems in his business. Minou is becoming disturbed and addicted to alcohol and tranquilizers. One night, Minou is out alone when she is attacked by a strange man, who cuts open her clothes and intimidates her sexually, and tells her that her husband has committed a murder.

Minou refuses to believe this, until she finds out that a man who has made a big loan to Peter's company, has now been found suddenly dead. She receives a telephone call from her attacker, who plays a tape recording that seems to be Peter participating in a murder. The attacker tells Minou that he will go public with this evidence if she does not come to his studio; at the studio she offers him money but he rejects that and demands that she participates with him in sadistic sex. This is captured on a hidden camera, thus giving him new material to continue blackmailing her.

Dominique, a close friend of Minou, initially seems to be trustworthy, but Minou discovers a pornographic photograph of her blackmailer in Dominique's possession. She denies any knowledge of the man, saying she bought the photo in a shop in Copenhagen.

Peter privately contacts a police inspector that he knows, to investigate what has been happening to Minou. When Minou leads the police to the blackmailer's studio, it has been emptied of all belongings; also the photograph has disappeared and Dominique refuses to corroborate that the photograph ever existed. Minou becomes desperate, unable to trust her husband or her best friend, leading to her taking an overdose of tranquilizers.

At the conclusion, the blackmailer comes to Minou's house at night (her husband is absent, as is the servant) with the intention to attack and kill her. In the middle of the attack, Peter comes into the house and shoots the blackmailer dead. Minou is wounded but still alive. Then suddenly the police arrive to arrest Peter – revealing that Peter had arranged a plot to murder his wife and cash in a large insurance policy that he took out for her life. Peter has employed the blackmailer (whom he met by chance on a trip to Copenhagen – hence the photograph) to intimidate his wife and arranged the final attack so that Peter would appear to be an innocent victim and thus claim the life insurance to rescue his business finances.

Peter kills the blackmailer during an attack on Minou, but is then arrested when it is revealed he orchestrated the blackmail and murder plot to collect insurance money.

The ending exposes Peter as the true architect behind Minou's torment, revealing his desperation to save his failing business by plotting his wife's death. The twist repositions victim and villain, turning Minou’s paranoia into justified suspicion and leaving her physically wounded but vindicated. The film closes the loop on its web of deception and trust shattered by greed.
