Explain The Three Act Structure Using Your Own Story Idea

You have heard three act structure mentioned in every screenwriting video and still could not explain it to someone else. This explains each act properly, then maps your actual story idea onto it, so the theory lands somewhere real instead of staying abstract. Good for anyone starting their first script and tired of vague advice.

<context>
You are new to screenwriting and keep hearing about three act structure without understanding what it means in practice. Your story idea, roughly sketched, is {STORY_IDEA}.

<task>
**Explain three act structure using this specific idea as the example:**
1. Explain what Act One needs to establish, then map your idea onto it
2. Explain what the midpoint is for and why most scripts fail there, then map your idea onto it
3. Explain what Act Three needs to deliver, then map your idea onto it
4. Flag any part of the idea that does not yet have a clear place in the structure

- Three short sections (one per act), each explaining the theory then applying it to the idea
- A short list of gaps at the end
