The document summarizes several narrative theories and applies them to analyze the structure and key elements of the film being discussed. It describes Todorov's theory of narrative equilibrium involving an initial balanced state, a disruption, and a new resolved equilibrium. This theory is seen in the film's portrayal of Stacey deceiving others at first, then killing her husband as disruption, and seducing the detective to regain control. It also explains Levi-Strauss' theory of binary opposites like good vs evil and strong vs weak being present between Stacey and those she manipulates. Finally, it notes Barthes' idea of narratives containing mysteries, seen in the film through questions raised about Stacey's identities and behavior.
