Researching the terms...

These terms are frequently seen and used when producing a script. Below are some general research I have gathered regarding the terms.

One Sentence Pitch
This is the key sentence that tells the audience what is the essence of your story. There are other variations, including One Paragraph, or Two Paragraph pitches. Its purpose is to grab the attention of the reader.

A one sentence pitch do not have to be extremely short, nor should it be hundreds of words long. The use of semi-colons and subordinating conjunctions can help to break up the parts in your single sentence. Take note that the end of the story is not to be divulge within the sentence.
