NARRATIVE STRUCTURE

Narrative - A chain of events linked by cause and effect and occurring in time and space.

Essentially, narrative is understanding the pattern of events that are happening. Something happened, which caused this to happen, which then made this happen, etc.

Within a narrative you have a story and a plot. A story is what happened  and the plot is how it happened. There are many different stories, and many different plots to many different stories. As an audience, we build the story from the plot by making assumptions and inferences by what's presented to us.

There's even a story and plot in the GED Achievement PSA. The plot shows us these celebrities taking various phone calls and giving these pep talks while also dealing with typical office situations such as Terry Crews stealing Jerry Stiller's sandwich. From this we can construe that the story is about a bunch of celebrities are working in a call center giving pep talks to people interested in getting their GED.

Even though these people are all rich and famous, they're taking the time out of their days to sit around a plain office building taking phone calls. Most people would consider this a boring job, but everyone is extremely happy to be doing this work and helping out. This shows the importance of getting your GED to the audience. If these people would be willing to do something like this, it must important.
