"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 (and sometimes the antagonist) is willing to do and sacrifice almost anything to pursue, protect or control, often with little or no narrative explanation as to why it is considered so important. 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. However, a MacGuffin can sometimes take a more abstract form, such as money, victory, glory, survival, power, love, or even something that is entirely unexplained, as long as it strongly motivates key characters within the structure of the plot."
