A plot device is an object or character in the story whose purpose is purely to drive the Plot, maintain its flow, or resolve situations within it. It could be something everybody wants to obtain, a device that must be destroyed, or an annoying teenager who must be protected at all costs.
It may also be an object or gadget introduced early in the story for the sole purpose of solving a sticky situation later on.
The term is commonly used in a derisory manner, on the grounds that the best stories are character driven, and using an object to make things happen is thus seen as a sign of bad writing. However, there are plenty of good stories which do indeed revolve around a plot device; equally, a plot device can very easily be used to generate conflict and thus spark a character-driven story.
Whenever someone uses the term derisively they often mean that something is being used as a gimmick (or worse, an Ass Pull) to Hand Wave resolutions to Plot Holes in a way that breaks the Willing Suspension of Disbelief

Lampshade Hangings and Other References:Almost by definition, stories have plot devices. Examples should be limited to lampshade hangings and references to the term.
- One Captain Mar-Vell comic, starring Genis-Vell, featured a very clever Kree fellow named "Plaht," whose "device" cleared away several plot inconveniences.
- In Redshirts, there is a mysterious device resembling a present-day microwave oven on the Intrepid called simply "the Box". Putting a sample from a xenobiological problem inside it will cause it to produce a solution just in time to provide a dramatic resolution to the current problem. Essentially, it's a handwave to make the "real world" experienced by the characters work out consistently with the "Narrative" cranked out by some modestly-talented writers.

- In The Dresden Files RPG, certain characters are noted as being "plot device level" characters. Most of them are considered Plot Devices because they're so ridiculously powerful that no Player Party would ever reasonably be able to take them on directly, making stats meaningless, and thus would have to outmanuever, work around, or run away from them; these include the Faerie Queens, Angels, and Dragons. A handful, however, are noted as being a Plot Device because they're so far down on the other side of the scale that they can only really provide one specific and specialized purpose, such as Elidee, a tiny pixie—even by pixie standards—who shows up briefly in one book to serve as a guide/flashlight for Dresden.

However, overusing a P.L.O.T. device can have serious consequences, and the more egregious uses can strain the very fabric of reality. P.L.O.T devices have fallen out of favor overall, but many a young and reckless pioneer has picked up a well-used P.L.O.T. device and run with it.
