Set in London, the film follows Carol Hammond (Bolkan), the daughter of a respected politician, who experiences a series of vivid, psychedelic nightmares consisting of debauched sex orgies and LSD use. In the dream, she commits a graphic murder of a neighbour whose life she is envious of (Strindberg) and awakes to a real-life criminal investigation into the murder of her neighbour.

The film was released in France as Carole, and was later re-released in the United States as Schizoid. The French release print is the longest at 101 minutes.
