Plot structure describes the arrangement of events in a story. Freytag's Pyramid models plot with five parts: exposition, rising action, climax, falling action, and resolution. The climax is the turning point of highest tension. Rising action involves conflicts that build to the climax, while falling action occurs after as a result. Modified Freytag's Pyramid extends before and after the primary rising and falling action. Key plot components include the inciting incident that begins the action, and the dénouement that concludes any remaining questions.
