This is the story of the yin and yang of fraternal twin sisters. Emanuela (Sherry Buchanan) is married to an abusive, insensitive man, and seeks solace with her fantasy dream lover, Marco ... a high school heart throb who perished in an accident. In contrast, her estranged sister Giovanna (Paola Montenero) runs a fetish brothel, reveling in the darker side of life. Emanuela's mother urges her to reconcile with her sister, but the initial encounter terrifies and repels the girl. By strange coincidence, she then encounters a young street merchant who is the spitting image of her Marco. Emanuela pursues the boy, only to find herself betrayed and raped. This trauma results in the disappearance of Marco - her only source of comfort - from her dreams. Without Marco, she can no longer endure her husband's brutality, and turns to her sister for a way out. Ironically, it was Giovanna who had orchestrated the cruel affair in an act of "tough love." Emanuela lures her husband, Roberto, to Giovanna's brothel so that he can witness her involvement in a staged orgy, and grant her a divorce. Giovanna is happy to oblige, taking matters a step further after Roberto has seen his wife's apparent infidelity ... beating and raping the misogynist. Having thus freed Emanuela from her bondage, the two sisters are physically and spiritually reunited as they were in their mother's womb - Giovanna's evil and Emanuela's goodness melding into one whole human being.
