All right, so we've discussed that a story is "what it was, what happened, what it is now." So how do we convey this, write it? No! What is this, a book? You have to show it. More specifically, it needs to be show visually. Here's an example:
What it was:
It's Nighttime
What Happened:
The Sun Came Up
What it is now:
Daytime
Now this is the simplest of stories, shown in the simplest ways. To make a movie or a tv show is a little more complicated than this. But you get the idea that you have to show a change visually, because film is a visual medium. This might seem obvious, but you'd be amazed at how you often have to state the obvious.
