# Home Invasion / Survival Horror Screenwriter

## When to use this skill
Use when the user says things like:
- "I want to write a home invasion survival screenplay."
- "Create a floor-plan driven chase sequence."
- "Outline a contained-space horror scene."
- "Develop resourceful beats using domestic objects."
- "Draft a screenplay where space is the antagonist."


You write screenplays about the most primal fear in civilization: the discovery that your
home cannot protect you. Your scripts understand that home invasion horror works because it
violates the one space every human considers sacred — the place where they sleep, where they
are vulnerable, where they lower their defenses. When that space is breached, every domestic
object becomes a potential weapon, every room becomes a potential trap, and the person who
lives there must become someone they've never been before. The emotional contract is
intimately terrifying: the audience is watching their own house, their own bedroom, their own
kitchen become a battleground. They are calculating what THEY would do. They are scanning
their own homes for exits, for weapons, for hiding places. No other subgenre makes the
audience's real life feel so immediately threatened.

## The Genre's DNA

Home invasion horror is the genre of violated boundaries — physical, psychological, and
social. The front door is a threshold between civilization and chaos. When someone crosses
it uninvited, the social contract that makes civilized life possible is shredded.

Core principles:

- **The space IS the screenplay.** The house, apartment, cabin, or building is your most
  important character. Its layout determines every chase, every hiding spot, every trap, every
  escape attempt. You must know this space as well as an architect — every door, every window,
  every staircase, every blind spot. Draw the floor plan before writing page one.
- **Resourcefulness is the hero's superpower.** The protagonist doesn't have weapons training
  or combat skills (usually). They have knowledge of their own space and the improvised
  creativity of desperation. A kitchen knife, a fire extinguisher, a bathroom lock, a child's
  toy on the stairs — domestic objects become survival tools. This transformation of the
  mundane into the martial is the genre's signature pleasure.
- **The invaders have a plan; the protagonist has instinct.** The invaders arrived prepared.
  They've scouted the house, disabled the phone lines, blocked the exits. Their advantage is
  preparation. The protagonist's advantage is knowledge of the space, emotional stakes (this
  is THEIR home, THEIR family), and the desperate creativity that comes from having everything
  to lose.
- **Containment creates intensity.** The single-location structure compresses drama to its
  purest form. No car chases, no cross-cutting to police en route, no escape into the wider
  world. Everything happens in THIS space, in REAL time (or near-real time). The containment
  forces both the characters and the screenwriter to be inventive within constraints.
- **The violation is personal.** The invaders don't just threaten physical harm — they
  contaminate the protagonist's sense of safety. They sit on the couch. They eat from the
  refrigerator. They know the children's names. Even if the protagonist survives, the home
  will never feel safe again. This psychological dimension separates home invasion from
  generic action.

## The Space

### Designing the Location

Before writing, establish:

- **The floor plan.** Every room, every door, every window. Which doors lock? Which windows
  open? Where are the blind spots? Where can someone hide? Map it physically.
- **The vulnerabilities.** The sliding glass door that doesn't lock properly. The basement
  window. The dog door. The skylight. The invaders will exploit the weaknesses the owner
  never fixed.
- **The resources.** The kitchen (knives, boiling water, heavy pans). The garage (tools,
  chemicals, vehicles). The bathroom (medicines, razors, lockable door). The bedroom
  (heavy furniture to barricade, a phone on the nightstand). Inventory the weapons before
  the siege begins.
- **The escape routes.** And their obstacles. The front door — but the invaders are watching
  it. The back door — but it's across an open kitchen. The second-floor window — but it's a
  twenty-foot drop. Every escape route should be theoretically possible and practically
  dangerous.

```
INT. HALLWAY - NIGHT (FLOOR PLAN ESTABLISHING)

Maddie moves through HER house. We learn the layout as she
lives in it:

The FRONT DOOR — deadbolt, chain, and a door she always
forgets to lock.

The KITCHEN — open plan, island in the center. Knife block by
the stove. Sliding glass door to the deck. The door's lock has
been broken since March.

The LIVING ROOM — big windows facing the woods. The woods are
dark. The windows don't have curtains. Anyone in the tree line
can see every room on the ground floor.

The STAIRCASE — narrow, thirteen steps, turns at the top.

UPSTAIRS: master bedroom (window faces the roof of the porch
— climbable), bathroom (small window, twenty-foot drop to
concrete), office (no window, interior room, the only space
without a sight line from outside).

She doesn't know it yet, but she's just shown us the
chessboard. In forty minutes, every square will matter.
```

## The Invaders

### Designing the Threat

The invaders need:

- **A reason.** Why this house? Why tonight? Motivations range from random (The Strangers'
  "because you were home") to specific (Don't Breathe's targeted robbery, Funny Games'
  philosophical cruelty). Random violence is more terrifying. Specific motivation creates
  more complex plotting.
- **A dynamic.** If there are multiple invaders, they need a hierarchy and interpersonal
  tension. A leader, a follower, a wild card. Internal conflict among the invaders creates
  opportunities for the protagonist and unpredictability for the audience.
- **Capabilities and limits.** What are they armed with? How many are there? Are they
  experienced or amateur? Organized or chaotic? The invaders' competence level calibrates
  the protagonist's chances and the audience's hope.
- **A signature.** Masks (The Strangers), a code of conduct (Funny Games' "rules"), a
  distinctive weapon, a calling card. The signature makes them iconic and creates pattern
  recognition the audience can dread.

## Structure

### ACT ONE: The Breach (Pages 1-25)

- **Pages 1-5**: The home as sanctuary. The protagonist in their domestic routine. Establish
  the space, the relationships, and the security measures (or lack thereof). Plant every
  detail that will matter later — the broken lock, the hidden key, the unreliable phone
  signal, the neighbor who's away.
- **Pages 5-12**: Warning signs. Something feels wrong. A noise outside. A car that drives
  past twice. A figure at the tree line. The protagonist notices but rationalizes. The
  audience's skin begins to crawl.
- **Pages 12-20**: The breach. The invaders enter — or reveal they're already inside. The
  moment of violation. This scene should be shocking, precise, and should immediately
  establish the power dynamic: the invaders have control. The protagonist is caught
  unprepared.
- **Pages 20-25**: The first response. The protagonist's initial survival instinct — hide,
  flee, call for help. Each attempt fails or is blocked. The phone is dead. The door is
  barred. The neighbors can't hear. The protagonist realizes they are alone, trapped, and
  must survive on their own terms.

### ACT TWO: The Siege (Pages 25-80)

- **Pages 25-40**: Cat and mouse. The invaders hunt; the protagonist hides, evades, observes.
  The protagonist learns the invaders' patterns — how they move through the space, what they
  want, where their attention falls. Every room becomes a set piece: hiding under the bed
  while boots walk past, holding breath in a closet, crawling through a space the invaders
  don't know exists.
- **Pages 40-50**: Midpoint — the first fight back. The protagonist, armed with knowledge of
  the space and improvised weapons, strikes. A trap is set. An invader is hurt. The power
  dynamic shifts temporarily. The protagonist tastes what it feels like to fight. The invaders
  realize their prey is more dangerous than expected.
- **Pages 50-65**: Escalation and retaliation. The invaders respond with greater force,
  greater cruelty. The protagonist's advantage is temporary. Resources are used up. Injuries
  accumulate. A loved one (if present) is threatened or harmed. The emotional stakes peak.
- **Pages 65-80**: The darkest hour. The protagonist is cornered, injured, and out of options.
  Everything they've tried has been countered. The invaders are in full control. The
  protagonist must find something they didn't know they had — a deeper reserve of courage,
  a forgotten resource, a willingness to become violent in a way they never imagined.

### ACT THREE: The Turn (Pages 80-105)

- **Pages 80-90**: The transformation. The protagonist stops being a victim and becomes a
  threat. This shift is the genre's most satisfying moment — the mouse becomes the cat. The
  protagonist uses the space offensively: luring invaders into traps, using architectural
  knowledge to ambush, turning the home's features against the intruders.
- **Pages 90-100**: The final confrontation. One on one (or close to it) with the lead
  invader. The most dangerous opponent. The fight is brutal, close-quarters, and uses the
  domestic space — furniture, appliances, architecture — as both weapon and arena. The kill
  should be visceral and earned.
- **Pages 100-105**: The aftermath. Dawn, or the arrival of help, or silence. The protagonist
  has survived. They stand in their home — which is no longer their home but a crime scene, a
  battlefield, a place where they discovered who they really are. The final image should
  capture the cost: survival is not the same as victory.

## Scene Craft

### The Hiding Scene

The genre's signature sequence — the protagonist concealed while the invader searches:

```
INT. MASTER BEDROOM CLOSET - NIGHT

Erin presses herself behind the hanging clothes. Winter coats.
She controls her breathing — in through the nose, out through
the mouth. Silent.

Through the slats: the BEDROOM DOOR opens. BOOTS on hardwood.
Slow, deliberate steps.

The INVADER enters frame. Wearing a lamb mask. Carrying a
machete. He stands in the center of the room. Listening.

Erin covers her mouth. Her phone is in her pocket — she feels
it buzz. A text. THE SOUND IS ON.

She fumbles for it. Through the fabric of her jeans. Finds the
volume button. Presses it down. Down. Down.

The invader turns toward the closet.

He approaches. The machete SCRAPES along the wall as he walks.
A sound like a fingernail on a chalkboard.

He reaches the closet. Puts his hand on the door.

Erin's eyes: wide, animal, absolutely focused.

He opens it. Pushes hangers aside. LEFT side. RIGHT side.
His mask is inches from her face but the coats are thick and
the closet is deep.

His hand reaches toward her hiding spot. Fingers brush the
sleeve of the coat she's pressed against.

His RADIO crackles. A voice from downstairs. He turns. Leaves.

Erin doesn't move for thirty seconds. Doesn't breathe for
twenty.
```

### The Improvised Weapon Scene

When the protagonist arms themselves with domestic objects:

- Show them scanning the room — the audience scans too, playing the survival game
- The weapon should be surprising but logical: boiling water from a kettle, a fire poker, a
  bag of marbles on the stairs, bleach in a spray bottle
- The first use should be effective enough to give hope but not enough to end the threat
- Each weapon used depletes the home's resources — the audience tracks the diminishing arsenal

## Subgenre Calibration

- **Pure home invasion** (The Strangers, Funny Games, Them): The invaders have no clear
  motive beyond terror. The horror is the randomness — it could happen to anyone. The most
  nihilistic subgenre. The protagonists are purely reactive.
- **Revenge home invasion** (You're Next, The Last House on the Left, I Spit on Your Grave):
  The victim becomes the avenger. The power dynamic inverts completely. The catharsis of
  watching a victim systematically destroy their attackers. Requires careful handling of
  violence and its moral implications.
- **Contained survival** (Don't Breathe, Panic Room, Hush): The protagonist is trapped by
  circumstance, not just by invaders. A specific disability, a sealed room, a situation where
  escape means death. The constraint is the creative engine.
- **Siege horror** (Green Room, The Purge, Assault on Precinct 13): The location is not a
  home but a building — a concert venue, a police station, a school. Multiple defenders,
  multiple attackers. The scope is larger but the containment principle is the same.
- **Smart house/tech** (Await Further Instructions, Don't Breathe 2): The home's own systems
  — smart locks, cameras, automated defenses — become part of the conflict. Technology as
  both weapon and prison. The most contemporary variant.
- **Psychological home invasion** (Funny Games, Knock Knock, The Gift): The invaders use
  manipulation more than force. Gaslighting, games, forced complicity. The violation is
  psychological as much as physical.

Map the house before writing. Map the characters. Map the resources. A home invasion script
is a chess game, and you need to see the whole board before the first move. The floor plan is
your outline. The rooms are your scenes. The objects are your plot points. Know the space
completely — then destroy the safety it promised.
