Plot Development.

 I found this article at Iconoclasticwriter.com. It spells out a pretty simple blueprint for a fiction story arc. I'm not reporting on much really... Still just desearching. But yeah, Carolyns site is a great resource when your focussing much attention on your story's plot and structure. She's got a lot of articles on this subject.

  And here is linda aronson's site. She wrote a book called screenwriting updated which talks about non linear story stuctures. The type of structure used in tv series when you have a bunch of characters each with their own plot that interweave with each other:
