Truth within a story

What is the "truth" within a story?

Is it the climax, the most memorable part, or the theme?
As a story teller is making the emphasis on certain parts of the story important?

If I were to divide a typical story into a 3 part structure,

1. Before climax
2. CLIMAX
3. After climax

This structure could fit into most experiences: before, during and after.

I would like to illustrate the relationship among these three.
But unlike books, in which form I have been working throughout this master program, I would like to create structures which cannot be reversed. I would also like to create the first stage, before climax, to be appreciated as it is, that the audience does not necessarily have to reach the climax.

By making the climax not easily accessible, the audience has a choice of viewing the work as it is or taking a step further. To reach the climax. The climax is an instant moment that only the person, or a group of audience that dare to break the first stage can experience the whole work. Otherwise the work remains at the same phase throughout the exhibition, and no one will ever experience the climax nor the after climax stage. On the other hand, if the climax of the work is reached then the aftermath of that event is the only remainder of the piece.
