Desideria falls madly in love with the sensual ambiance of the ancient, teeming city. She begins a passionate affair with a handsome Turkish guide, Yaman. Upon her return home, she learns that she is pregnant. Ramiro agrees to support the child, but unfortunately it dies in infancy and the grieving Desideria flees for Istanbul to find her lover. She finds him and they renew their torrid affair. Later she learns some distressing things about Yaman, but this does not stop her from becoming his sexual slave and a call girl for wealthy carpet sellers."
