Todorov's theory proposes that narratives follow an equilibrium-disruption-new equilibrium structure, where a story begins with a stable situation, faces some disruption, and ends with resolution or a new stability. The example of Titanic shows the initial stability of the luxury ship, the disruption of Jack and Rose's romance and the sinking after hitting an iceberg, and attempts to survive and restore order. The document discusses applying Todorov's theory to a story involving a character who hears unexpected sounds at school, facing disruption and seeking resolution.
