Working out the main plot points

In order to create my synopsis, I need to flesh my storyline out further so I know how the plot will go. 

My logline was: 

When lonely village postman Ted starts receiving anonymous love letters he goes on a clumsy adventure to find his secret admirer

In order to do this, I laid out the three act structure in order to work out the plot and make sure it follows the typical conventions:

Act 1:

• Beginning
• Inciting incident 
• Second thoughts

Act 2: 

• Obstacles
• Big twist
• Obstacles
• Crisis

Act 3:

• Descending action 
• Wrap-up
• End

I then took these points and keeping in mind the ten-minute limitations of this task, wrote out my plot points:

Act 1:

• Beginning- introduced to Ted, our postman, and his day-to-day job
• Inciting incident- finding the love letter
• Second thoughts- doesn't believe it to be for him, but later decides to follow the clues (after an action which shows how lonely he is, e.g. setting up one dinner place and looking at the empty chairs)

Act 2:

• Obstacles- on his round struggles with the clue, believes it to be the shop lady (she's very friendly to him and slightly flirty) 
• Big twist- not the shop lady
• Obstacles- receives a new clue, leads him to the village hall cleaner 
• Crisis- it's not her and there's no new clue 

Act 3:

• Descending action- after a moment of pessimism finds a new clue in front of his house, leads him to the lady opposite, often seen tending to her garden
• Wrap-up- all the clues become clear
• End- happy :)
