Yes, from the man who brought you Unicorns Doing Horrible, Horrible Things comes a most useful post about Plot. Thanks, Peter M. Ball.

I am currently printing this out and sticking it on my wall.

EVERYTHING I KNOW ABOUT PLOT IN 1,069 WORDS OR LESS

1. PROTAGONIST, ANTAGONIST – FIGHT!

Most plots hang off a pretty simple dynamic designed drive a story forward. It goes something like this: your protagonist wants something really badly; your antagonist denies your protagonist the thing they really want; delicious, awesome conflict ensues. Take Lord of the Rings as an example – Frodo wants to live a nice, ordinary life in the shire; Sauron will destroy the world if he does that; therefore there is a whole lot of walking and fighting and stuff.

The rest is here.
