Part 1: Introduce character and a serious problem. Do NOT give the entire life history of your character. The problem can be either threat or a challenge, but it must be a serious challenge.
Part 2: Problem becomes worse. Character attempts to solve problem. The SAME character introduced as the main character
Part 3: Resolution. This can go three different ways:
The main character wins: He or she solves problem or defeats the enemy.
The main character loses: He or she dies tragically trying to solve problem or defeat the enemy.
Mixed: The main character fails to win or solve the problem, but he or she learns a lesson about life in the process.
