Reiko, a professional model, has been groomed by the editor of a golfing fashion magazine to become a golf pro. Her victory during her first professional competition wins her the approval not only of her mentor, but a whole new television audience, where she makes regular appearances clad in a bikini and wielding a 9-iron. Everybody wants a piece of Reiko, including neighbor-from-hell, Mrs. Semba, who begins stalking her. One evening Mrs. Semba confronts and blackmails her. With her career seriously threatened, Reiko has no choice but to concur. However, the blackmailer begins to abuse her power and Reiko finds herself succumbing more and more to her violent fantasies.
