A logline is a one-to-two sentence summary that tells a reader who the story is about, what they want, what stands in their way, and what's at stake. Knowing how to write a logline well is one of the most practical skills a screenwriter can develop, because if you can't compress your story into two sentences, you probably don't know your story as well as you think you do.
The good news is that loglines follow a learnable structure. Once you understand what every strong logline contains, you can draft one in under an hour, stress-test it, and refine it until a producer, manager, or contest reader leans forward instead of moving on.
What a Logline Actually Does
A logline is not a tagline. Taglines are marketing slogans designed to create mood. Loglines are working documents designed to communicate story. When someone asks what your script is about, a logline is your answer. It appears at the top of a query letter, in a pitch document, in a contest submission, and often in the first line of an email to a manager.
A logline does three things at once. It signals genre and tone. It demonstrates that the story has a clear engine. And it shows that the protagonist has a specific problem to solve. If your logline doesn't do all three, it needs another pass.
The Core Formula
There are several logline templates floating around, and most of them reduce to the same skeleton:
- Protagonist defined by a relevant trait or situation (not just their name)
- Inciting incident or situation that disrupts their world
- Goal they must now pursue
- Antagonistic force or obstacle that makes the goal hard to reach
- Stakes that make the outcome matter
You rarely need every element spelled out as a separate clause. Good loglines weave them together so the sentence reads naturally, not like a checklist. The formula is a diagnostic tool, not a mad-lib.
Logline Examples With Analysis
The fastest way to learn the form is to read produced loglines alongside the films they describe and identify what each word is doing.
The Silence of the Lambs: "A rookie FBI agent must seek the help of an imprisoned cannibal to catch a serial killer who is skinning his female victims."
Protagonist: rookie FBI agent (vulnerable, inexperienced). Goal: catch the killer. Obstacle: she must rely on a dangerous, imprisoned predator. Stakes: women are dying. Genre: clear. Notice there are no character names. Names mean nothing in a logline until the script is already famous.
Whiplash: "A young jazz drummer at a prestigious music conservatory is pushed to his breaking point by a brilliant but abusive instructor."
This one leans on internal stakes. The obstacle is the antagonist himself. The tension is psychological. The genre signals drama with intensity. It earns attention in one sentence.
Get Out: "A young Black man visits his white girlfriend's family estate and discovers they harbor a terrifying secret that puts his life in danger."
The racial dynamic is in the setup, doing thematic work without announcing itself. The discovery structure creates mystery. Stakes are clear. Tone is immediately unsettling.
Bridesmaids: "A broke, romantically adrift woman spirals when her best friend's engagement forces her to compete with a wealthy, charismatic bridesmaid for the role of closest confidante."
Comedy loglines need to carry the absurdity of the situation, not just describe events. The word "spirals" does emotional and tonal work at the same time.
The Five Most Common Logline Mistakes
- Too vague. "A man must save the world" is not a logline. Specificity creates intrigue. What kind of man? What specific threat? What stands in his way?
- Too much plot. Loglines describe situation and stakes, not the sequence of events. If you're using the words "then," "but then," or "finally," you're summarizing a synopsis, not writing a logline.
- No stakes. A goal without consequence is an errand. The reader needs to feel that failure matters.
- Passive protagonist. Your character should be doing something, not having things happen to them. "A woman is kidnapped" is weaker than "A woman escapes her kidnapper only to discover she's protecting the wrong secret."
- Describing theme instead of story. "A story about the price of ambition" tells me nothing. Show me the story. The theme will come through if the story is right.
How to Find Your Logline Inside Your Script
If you've already written a draft, the logline is hiding in your Act Two engine. Ask yourself: what does my protagonist want, and what specific force keeps them from having it? The answer to that question, framed with the right stakes, is usually your logline.
If you can't answer that question cleanly, that's diagnostic information. It often means the script has a structural problem, not a logline problem. A logline crisis is frequently a story crisis in disguise. Tools like beat sheets can help you find and fix the underlying issue before you try to pitch. The Save the Cat beat sheet is worth revisiting if your Act Two feels soft, because a weak midpoint or low point almost always shows up in a vague logline.
If you're mid-draft and struggling to articulate your story's spine, Better Draft offers structural analysis that reads your script and identifies where the engine is stalling, which is exactly the kind of honest feedback that makes your logline click into place.
Testing and Refining Your Logline
Write five versions. Seriously. Write one that's purely functional, one that leads with the antagonist, one that leads with stakes, one that's a single sentence, and one that's two. Then read them aloud. The version that sounds most like a story being told confidently is usually closest to right.
Then say it to someone who has never read your script. If they ask a question you expected, the logline is working. If they look confused or ask what the movie is actually about, something fundamental is still missing.
A logline also evolves as the script does. Draft one early to guide your writing, but plan to revise it after every major structural pass. The final logline for a finished script is almost never the logline you wrote before page one.
FAQ
How long should a logline be?
One to two sentences, ideally under 50 words. If you find yourself needing three sentences to cover the basics, the story may not have a clean enough spine yet. Tighter is almost always better.
Should I include the title in my logline?
In a query letter or pitch document, the title appears separately above the logline. Inside the logline itself, no. Let the story speak. The title gets its own line and its own job.
Do loglines work the same way for TV pilots as for feature films?
For a pilot, your logline needs to capture both the episode engine and the ongoing series premise. You might write one sentence for the pilot's specific conflict and one for the show's recurring world or central tension. The same principles apply: protagonist, goal, obstacle, stakes.
Can a logline give away the ending?
Not usually. Loglines describe setup and central conflict, not resolution. You want the reader to feel compelled to ask what happens next, which means leaving the outcome open. Think of it as an invitation into the story, not a recap of it.
Once your logline is solid, the rest of your pitch materials get easier. A strong premise stated clearly is the foundation for a query letter, a one-page, and eventually a meeting. If you want honest structural feedback on the script behind the logline, Better Draft's coverage and analysis tools are built to help you finish a script worth pitching, not to write it for you.
