A spoiler is a summary or description of a narrative (or part of a narrative) that relates plot elements not revealed early in the narrative itself. Moreover, because enjoyment of a narrative sometimes depends upon the dramatic tension and suspense which undergird it, this early revelation of plot elements can "spoil" the enjoyment that some consumers of the narrative would otherwise have experienced.
