MacGuffin 麦高芬
（重定向自MacGuffins）
In fiction, a MacGuffin (sometimes McGuffin or maguffin) is a plot device in the form of some goal, desired object, or other motivator that the protagonist pursues, often with little or no narrative explanation. The specific nature of a MacGuffin is typically unimportant to the overall plot. The most common type of MacGuffin is an object, place, or person; other, more abstract types include money, victory, glory, survival, power, love, or some unexplained driving force.
