Carol Hammond, the sexually frustrated wife of a successful London lawyer, is having bizarre, erotic dreams about her uninhibited neighbour, Julia Durrer, who presides over noisy, sex and drug filled parties in the house next door. One night, Carol's dreams culminate in violent death and she wakes to find her nightmares have become reality - Julia has been murdered and Carol is the main suspect.

This frightening discovery is just the beginning of a labyrinthine psycho-sexual shocker which takes the viewer on a wild ride through a series of frequently breathtaking set-pieces that set new standards for the Italian thriller. On its original release the film was cut in many countries and its makers were even threatened with prosecution over some of the startlingly realised scenes of gore. - Text Courtesy of Mondo Macabro
