We hear these phrases used interchangeably all the time. Well-intentioned advice given by so many writing teachers and gurus becomes migraine material when "premise line" and "log line" are actually used in the same sentence referring to the same thing. I’ve actually heard this done by story consultants, “Yes, you need a great premise line. In fact, the log line is the key to any good premise. So, take the time to develop a great premise line.” Still running screaming down the hall, FYI.
The premise line is your story. Period. The premise line is a complex and subtle construction that reveals not just a main character and an adventure; it actually delivers the basic structure of the story to the reader-viewer. The art of the premise line is the art of precision and clarity of ideas. A well-formed premise will “click” when you read it to someone and they will say, “Yeah, I see that story. I’d read that.” They “see” the story in just a few short lines. But, getting those lines just right might take hours, days, or even weeks. I’ve known some to take months. What is it they “see”?
The premise line gives them a clear vision of a protagonist acting with a purposeful desire toward a goal that is opposed by some force, and all this leading to some dénouement. This is a simplistic definition, but it captures the essence of what a premise line accomplishes. I will be writing a later post that breaks this down specifically with examples, but for now, know that the premise line is the structure of your story told as a single sentence (that’s right—1 sentence; and not a long run-on sentence sprinkled with comma splicing!) that has forward movement and gives a sense of the story’s beginning, middle, and end (no, don’t give away the ending).
Here is an example of a good premise line (three guesses what book/movie):
When the innocent, youngest son of a powerful mafia godfather discovers his beloved father has been shot as part of a turf war, he agrees to join the family to exact revenge and re-establish the family’s honor, until his actions force him to cross a line he was never meant to cross, dooming him to become the next Godfather.
The log line, unlike the premise line, does not show the overarching shape of your story, it does not give you the action line of the protagonist, nor does it give you a sense of the big picture. No, the log line’s job is to grab you and get your mind and emotions churning. There are seven components to a high-concept idea:
- High level of entertainment value
- High degree of originality
- High level of uniqueness (different than original)
- Highly visual
- Possesses a clear emotional focus (root emotion)
- Targets a broad, general audience, or a large niche market
- Sparks a “what if” question

- A monster shark terrorizes a small coastal town [Jaws, Peter Benchly]
- A cop battles uber-thieves when they take over an office building. [Nothing Lasts Forever, Roderick Thorp (film: Die Hard)]
- A young boy discovers he’s a wizard and goes off to wizard school. [Harry Potter, J.K. Rowling]
- A man saves a pregnant woman in a world where women no longer give birth. [Children of Men, P.D. James]
These are the differences between the two tools. It does not take a rocket scientist to see how they work together to form a powerful effect in pitching a story. One grabs you and the other satisfies the “what if” with a bit more detail. Together they sell the story and get you that next meeting.
So, to summarize: premise line and log line are two different tools that work synergistically to create a powerful image of your story. They were built to work together, not separately. If you build them well, you will take many lunches—and you won’t have to pay either.
Now go be brilliant.
