Because, let's face it, plots are hard.
You've got your inciting incident, your rising action, your dramatic turning point, and your denouement. But do you really get it?

They're the MacGuffits, the Red Herrings, and the Chekhov's Guns. They're the plot's unsung heroes, the ones that make the story go 'round.
Learn more about them at MacGuffit, Red Herring, or Chekhov's Gun.
