Your premise, and why it gets locked

The premise is your film in one sentence. Not a summary, not a pitch — the irreducible thing that makes it this film and not another one.

It is the first thing the Story Room asks for, and the only thing it lets you lock.

Why one line

Because a premise you cannot say in one line is usually two films, or none. The discipline is the point: if the sentence needs an "and also", something in the story is not carrying its weight yet.

It is also the thing you will check every later decision against. A scene that does not serve the premise is not necessarily a bad scene — but you should have to notice you are keeping it.

What the Compass asks for

Open Story Room → Compass. Alongside the one-liner:

• Logline — the pitch in a sentence or two: who wants what, and what stands in the way.
• Theme — what the story argues. Not a topic ("family") but a claim ("loyalty costs more than it pays").
• Genre and tone — a few words each. Tone is the one people skip and the one departments ask about first.
• Constraints — what the story has to work within: budget, locations, a cast you already have, a runtime, a real event it cannot change.
• Ending type — happy, sad, bittersweet, open, part two, or anthology. Choosing this early is uncomfortable and useful: most story problems are really disagreements about the ending that nobody has had out loud yet.

Change any of them and press Save — only what you changed is saved.

Locking

Once you are sure, you can lock the one-liner.

Locking is deliberate and it is permanent — there is no unlock. That sounds harsh for a text field, and it is the point: the premise is the one thing that should stop moving once the work starts. If it is still moving, the film is still being decided, and locking it is a way of saying out loud that it is not.

Locking freezes the one-liner only. The logline, theme, genre, tone, constraints and ending can still be changed and saved afterwards.

Next: the story spine — the beats that carry the premise from beginning to end.
