Tricked by the promise of a scholarship to study in America, the pretty young Ju-Won is taken from her home in South Korea to Portland, Oregon. The manager of an illegal massage parlor, the Lucky Flower, expects her to give 'happy endings' to customers. With no lodging or money, and in debt, Ju-Won becomes a masseuse and sex worker at Lucky Flower. During a sexual encounter with a corrupt policeman she calls Nasty Eyes, she finds herself aroused when placed in bondage and dominated. She later enters into a submissive relationship with a wealthy real estate broker who buys Ju-Won's freedom only to indulge in his own fetish of watching her give pleasure to multiple men. She performs sex acts for her Dom's pleasure and profit before he abandons her at Lucky Flower. When Nasty Eyes rescues her from a police raid, she ends up with Dr Kang, a kindly psychiatrist, who offers her a conventional life. But is that what she really wants? Will Ju-Won finally find her own happy ending?
