Psychological thriller

Need help for a script for a psychological thriller act

for genre: psychological thriller 

notes: 

Desired plot: inspired from two movies po sa netflix “the woman in the window” and “the watcher” 

Specify 3-5 characters and their roles my ideas (main character “the girl/wife” , creepy ex-husband, psychologist involved, etc.)

Must have 5 scenes (medium-length scenes please)

Scene 1: flashback

Scene 2: focus on other characters

Scene 3: climax (receiving creepyletters, threats, reporting to authority, etc.)

Scene 4: falling action

Scene 5: end

for settings: the main character leaves in a country side, but moves to a different apartment to avoid the stalker (ex-husband)

thank you so much! xoxo

!!!!!! each scene should contain scripts for every character you wish to include in each scene (actual script, not description of the characters) thank you so much, this would mean a lot to me.
