In fiction, a plot hole, plothole or plot error is a gap or inconsistency in a storyline that goes against the flow of logic established by the story's plot. Such inconsistencies include such things as illogical or impossible events, and statements or events that contradict earlier events in the storyline.
While many stories have unanswered questions, unlikely events or chance occurrences, a plot hole is one that is essential to the story's outcome. Plot holes are usually seen as weaknesses or flaws in a story. However, certain genres (and some media) that require or allow suspension of disbelief—especially action, comedy, fantasy, and horror—are more tolerant towards plot holes.
