Emmanuelle (Angie Quick) goes to London's Soho District. It is the place of trickery, sex and a notoriously sordid section of town. She finds there Kate (Julie Lee) and her husband Paul Benson (Kevin Fraser), who is a photographer and struggling to pay the bills. Together, they try to succeed. Kate is forced to take a job in a naked cabaret. They also try to book their profit by blackmailing a film magnate. Meanwhile, filled with jealousy, her husband starts an affair with Emmanuelle. Finally, they include Kate also in their amorous acts, and all concerned are now frantically trying to fulfill their basic instincts of sex and desire.
