Over 200 literary terms, Shmooped to perfection.
A plot, in any form of literature, is made up of scenes.
In drama, it's the subdivision of an act. Usually, it's defined by having a single setting and a certain set of characters.
Of course a scene can also refer more loosely to a series of events within a certain amount of time in a work of literature—a conversation between two characters, the climactic battle at the end of a war, or even just the protagonist getting out of bed in the morning.
