Story Structure

Three-Act Structure

Act One (Setup) - ~25%

  • Opening Image - Visual that sets tone
  • Theme Stated - Hint at the theme
  • Setup - Introduce protagonist, world, stakes
  • Catalyst - Inciting incident
  • Debate - Protagonist hesitates
  • Break into Two - Protagonist commits to journey

Act Two (Confrontation) - ~50%

  • B Story - Secondary storyline (often romance/friendship)
  • Fun and Games - Promise of the premise
  • Midpoint - False victory or defeat, raises stakes
  • Bad Guys Close In - Pressure increases
  • All Is Lost - Lowest point
  • Dark Night of the Soul - Protagonist confronts failure

Act Three (Resolution) - ~25%

  • Break into Three - Solution discovered
  • Finale - Confrontation and resolution
  • Final Image - Opposite of opening, showing change
