"Falling action" is a plot element in literature that follows the climax of a story and starts the plot toward its resolution. Many of the questions about the story start being answered in the falling action.
Once the climax, or high point of interest, has been reached, the story starts tying up the loose ends and coming to an end. This part of the story, the falling action, is the opposite of another element, the rising action, which occurs earlier in the plot and presents the reader with all the conflicts and questions. Most short stories and tragedies have an exposition or introduction, rising action, climax, falling action and resolution.
