Blue Ecstasy in New York (1980)

BLUE ECSTASY is an unusual film that explores with candor the sexual conflict acted out by dual personalities inhabiting the single body of a young woman. Veronica has an unusual companion - Ronnie who is the exact opposite of Veronica. Her friend Niki is a fun loving person and cannot at all understand Veronica's prudishness. At Niki's suggestion, she and Veronica go shopping for some new, sexy clothes for Veronica's changing personality - which becomes the catalyst for a film revealing many layers of sexual denial and redemption.
