A plot summary is a condensed version of a story that outlines the main points of the narrative. A plot summary typically includes the main characters, the setting, the conflict, and the resolution. The term 'SCENARIO' is often used to refer to a detailed description of the plot of a story, while 'SYNOPSIS' is used to refer to a brief overview of the plot. Both terms are used to provide an overview of the story without giving away too many details.
