Nadia arrives with her white cat to collect a diary that belonged to her dead sister, Vera. From it Nadia learns of her sister's demise. Vera falls in love with Nick, a callous pimp who forces her to make love to an old lecher, and to satisfy a voyeur Nick has her commit sodomy. The disillusioned Vera is spurned by Nick when she discovers that she is pregnant, and, wandering the streets, she is killed by a car. Bent on revenge, Nadia lures the unsuspecting Nick to her villa, where he is drugged and chained in a secluded cell. He is forced to watch Nadia make love to her boyfriend, a delivery boy, and Nick's girl friend. Frustrated, Nick is driven nearly mad observing the bizarre scene--until Nadia suddenly enters the cell and castrates him.
