A major movement in a story, often ending on a shift in goal or stakes.

An act is a stretch of story bounded by a turn in goal, strategy, or stakes, not a fixed page count. Many novels use three acts; others use two, four, or none at all while still changing pressure over time.

Acts help you diagnose sag: if the middle feels endless, you may need a midpoint turn or a clearer act break rather than more events.

Why it matters

Act language lets you talk about macro shape in revision and align Scene Builder sequences with dramatic movement.

Common pitfalls

Treating acts as rigid page counts instead of dramatic turns.
Ending an act on a quiet beat with no shift in goal or stakes.
Labeling acts without checking whether each movement has its own dramatic question.

Example only

Act one ends when the courier burns the safe house. The hero can no longer pretend this is someone else's problem.
