Applying Barthes' Theory To Our Film

Barthes said that every film raises questions (enigma codes) and some actions lead to other acttions in the film (action codes) to create suspense.

Action codes:
Showing boots walking
Laying out tools
Guy being held hostage
Camera fading to black at the end

Enigma codes:
Why does she fire a blank at his head?
Why is he being held hostage?
What tool will she pick?
Why does she need so many tools?
