Carol Hammond, the sexually frustrated wife of a successful London lawyer, is having bizarre, erotic dreams about her uninhibited neighbour, Julia Durer, who presides over noisy, sex and drug filled parties in the house next door. One night, Carol 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. Was she set up, or did she really do it?
