Todorov's theory of narrative structure proposes that all stories follow five stages: 1) an initial state of equilibrium, 2) a disruption to that equilibrium, 3) recognition of the disruption and the need to address it, 4) an attempt to repair the disruption, 5) a reinstatement or establishment of a new equilibrium. The document then provides examples of how these stages could apply to a horror film involving a teenage girl being stalked by a psychotic killer at her school.
