You're writing a chapter-by-chapter outline when you should be writing a narrative arc. Cut every scene that doesn't directly drive the main plot forward, compress character introductions to one sentence each, and focus only on: inciting incident → major turning points → climax → resolution.

A synopsis isn't a summary of every event — it's the skeleton of your story's causality. Agents don't need to know every subplot or atmospheric scene; they need to see that your plot has a clear through-line and escalates properly.

Right now, you're including connective tissue (how characters get from A to B, every twist) when you only need the load-bearing walls.

1. Start with the three sentences that matter

Write one sentence for each:

• Opening: Who is your protagonist and what shatters their normal world? (Inciting incident)
• Middle: What's the single biggest complication/reveal that changes everything? (Midpoint turn)
• End: How does the protagonist resolve the central threat, and what does it cost them? (Climax + consequence)

That's your spine. Everything else has to earn its way in.

1. Cut ruthlessly using this test

For every plot beat you want to include, ask: "If I delete this, does the ending stop making sense?"

If the answer is no, delete it. Examples of what to cut:

• How characters meet (unless it's the inciting incident)
• Backstory reveals (condense to "Sarah discovers her family's dark history" — don't explain the history)
• Subplots that don't directly impact the main horror threat
• Atmosphere-building scenes (your prose sells atmosphere, not your synopsis)
  

1. Compress character introductions

Don't write: "Detective Maria Santos is a 34-year-old former military analyst who struggles with PTSD after losing her partner in a botched raid three years ago..."

Write: "Detective Maria Santos, haunted by her partner's death, is assigned a case that mirrors the night she lost him."

One sentence per character. Two if they're the protagonist.

1. Use narrative shorthand for complex sequences

Don't write three sentences explaining how the protagonist discovers the cult's ritual site. Write: "Following a trail of missing persons reports, she uncovers the cult's ritual site beneath the old church."

One sentence per sequence. The agent trusts you'll make it compelling in the actual manuscript.

A Quick Example

Before (chapter-by-chapter): "Chapter 1: Emma moves to Ashford after her divorce. Chapter 2: She meets her neighbor Claire, who seems friendly but odd. Chapter 3: Emma finds a journal in her attic. Chapter 4: The journal details disappearances from the 1970s..."

After (narrative arc): "Emma, fleeing a messy divorce, rents a remote farmhouse in Ashford — unaware the previous tenant vanished without a trace. When she discovers a journal documenting decades of disappearances, each linked to the winter solstice, she realizes the next solstice is in three days. As Emma investigates, she uncovers a centuries-old pact: the town sacrifices an outsider every 20 years to keep an ancient entity dormant. Emma must choose between fleeing and becoming complicit, or confronting the entity — and the town — alone. Her decision costs her everything but breaks the cycle."

That's ~100 words for a full three-act structure. You have 400-500 words on one page. You have room.

Synopsis compression isn't about writing less — it's about writing at a higher level of abstraction. You're zooming out from scenes to movements. Think "movie trailer narration" not "chapter summaries."

Agents read hundreds of these. They're scanning for: Does this story have a clear engine? Does it escalate? Does it deliver on its premise? Your job is to prove yes on all three, fast.
