What is Plot: Definition and 714 Discussions

In a literary work, film, story or other narrative, the plot is the sequence of events where each affects the next one through the principle of cause-and-effect. The causal events of a plot can be thought of as a series of events linked by the connector "and so". Plots can vary from the simple—such as in a traditional ballad—to forming complex interwoven structures, with each part sometimes referred to as a subplot or imbroglio. In common usage (for example, a "movie plot"), however, it can mean a narrative summary or story synopsis, rather than a specific cause-and-effect sequence.
Plot is similar in meaning to the term storyline. In the narrative sense, the term highlights important points which have consequences within the story, according to Ansen Dibell. The term plot can also serve as a verb, referring to the writer's crafting of a plot (devising and ordering story events) or to a character's planning future actions in the story.
