Julia, the beautiful wife of a company president, is kidnapped, imprisoned, and raped by employees of a rival company who are plotting to blackmail her husband. Gagged and collared, Julia is constantly trained in an iron cage, awakening her masochistic tendencies and reducing her to a sex slave. When she is taken to her husband's home and raped in front of him, she shakes her hips as if to demonstrate, and her sexual fluids flow with pleasure. Thus, the marriage falls apart. Now no longer of any use, Julia is sold off as a sex slave to those in power.
