A McGuffin is a plot device, object or anything of that sort that is needed to do something "important" to make the story happen. E.g. "To kill the bad guy you HAVE to find this sacred magical thingy that only appears every 20 years, at this one place, at this one time. Why? BECAUSE WE NEED TO FILL 90 MINUTES WORTH OF MOVIE SO GET ON WITH IT!!!!!".
