The main characters are
introduced and the setting
is described.
Something begins to happen,
maybe a new character is
introduced or the story
moves to a different setting
and the story gets going.
Something goes wrong - a
problem of some kind
affects the main character,
or one of the characters in
the story.
The problem is solved,
maybe a new character is
introduced who sorts things
out or the main character
changes things, or the
setting changes in some way.
All the loose ends are tied
up, and maybe the character
thinks about what has
happened to them - have
they learned anything, have
they changed in some way?
