Writing my treatment- theory

Although I have initial ideas to write a treatment I looked at how to structure a storyline.
This will prove useful when structuring my treatment.
The following link shows Nigel Watt's “Eight-Point Story Arc”which is seen as very helpful when structuring a story...

 HOW TO STRUCTURE A STORY

This showed me that my treatment/storyline should...

• Introduce the scene, setting characters in the first act (stasis) 
• Have a problem and the quest to solve it in the second act/ middle part of the story (trigger and quest)
• Have a climax and solution in the third act/final part of the film.
