Noir et Blanc (1986)

Synopsis
A white accountant finds himself irresistibly drawn into a sadomasochistic relationship with his black masseur in this distinguished film debut from French filmmaker Claire Devers. The story contains little dialog and is filmed in black and white. The accountant is a quiet married man who has been hired to work on the books of a local health club. He is not interested in extramarital sex, only his work. Later his boss suggest he try a massage at the club. A cautious man, the accountant is at first bashful as the enormous masseur begins working on his tense muscles. Soon he finds himself hooked on these evening sessions that become increasingly violent (but not sexual) as time passes. ~ Sandra Brennan, All Movie Guide
