‘It Comes at Night’ Film Theories: Possible Meanings

My wife is a big Christopher Abbott fan, so It Comes at Night was a definite in-theater experience for us. It was a fun watch—although a bit ambiguous for my taste—and I came away with some thoughts about what it all means.

It’s hard to mistake this for a surface-level film. From nearly the opening scene, it’s clear we’re watching some kind of extended allegory. I’ve summarized my It Comes at Night theories below, but I hope you’ll add some to keep me thinking.

Top Theories About the Meaning and Themes of ‘It Comes at Night’ (2017)

1. Fear as the Real Monster

Theory: The film’s title and setup suggest a monster “out there,” but in truth, the biggest threat is the family’s own paranoia and mistrust.

• Why It Fits: The characters are so terrified of the unknown (the virus, intruders) that they turn on each other. Instead of a physical beast, it’s paranoia—arriving each night in Travis’s nightmares—that ultimately drives them to kill.
• Key Moments: Paul’s extreme suspicion of Will, and the final act’s violent escalation, show how fear becomes the catalyst for tragedy.

2. The Virus as a Metaphor for Moral Decay

Theory: Although the virus is a literal threat, it also symbolizes how society—and basic morality—breaks down under extreme stress.

• Why It Fits: Each time a character suspects another of being infected, they begin to weigh survival against empathy. The more uncertain they are, the more violent and selfish they become, “infected” by fear.
• Key Moments: Bud’s mercy killing establishes a grim baseline; later, Paul’s decision to kill Will’s family suggests the virus has poisoned everyone’s capacity for trust.

3. Travis as the Audience’s Conscience

Theory: Travis, with his recurring nightmares and quiet observations, represents a moral center that tries to see beyond suspicion and violence.

• Why It Fits: While Paul and Sarah set strict survival rules, Travis is more compassionate and curious—watching, listening, and wanting to connect (for instance, with Kim). His nightmares reflect an empathy that can’t reconcile survival with brutality.
• Key Moments: Travis’s heartbreak over losing Stanley (the dog) and his attempts to check on Andrew’s well-being show he’s still seeking human connection while the older generation calcifies in fear.

4. Generational Trauma & Cyclical Violence

Theory: The movie opens with the euthanizing of Bud (Travis’s grandfather) and ends with Travis dying in front of his parents—suggesting a grim cycle of death passing down through the family.

• Why It Fits: The cycle intensifies when Will enters the picture. Paul tries to maintain order but ends up committing acts as ruthless as the horrors they fear outside.
• Key Moments: Bud’s death sets a precedent for how the family deals with sickness (and later, outsiders). Travis’s own demise completes the cycle, leaving Paul and Sarah alone, infected, and trapped in their own regret.

5. The Ambiguous ‘It’—Outside Threat or Inner Darkness?

Theory: The film’s title, It Comes at Night, might refer to a literal virus or prowling threat in the darkness, or the psychological dread that creeps in every time night falls, when nightmares and mistrust take hold.

• Why It Fits: We never see a definitive monster, and the virus itself remains invisible. Nighttime is when tensions spike, illusions appear, and violence erupts.
• Key Moments: Travis’s nightmares almost exclusively strike at night, underscoring that perhaps “it” is the darkness in each character’s mind.

6. Breakdown of Civilization in Microcosm

Theory: The movie is a microcosm of how societal structures collapse when people isolate themselves out of fear. The house becomes a mini-society under constant stress.

• Why It Fits: Paul sets up rules (like a dictator or strict leader) to protect his household. Will, Kim, and Andrew threaten the fragile system with new needs and possible contamination. The resulting conflict is akin to a societal meltdown, just on a small scale.
• Key Moments: Paul’s controlling nature—tying Will to a tree for interrogation, imposing curfews, insisting on armed readiness—mirrors authoritarian measures that arise when panic overrides empathy.

7. Moral Boundaries vs. Survival Instinct

Theory: It Comes at Night asks if moral codes can survive when mere survival is at stake. Every character must wrestle with how far they’re willing to go to protect their own.

• Why It Fits: The family’s “line in the sand” keeps shifting. Initially, Paul grants Will water and trust—but ends by mercilessly killing Will’s family. It suggests that given enough pressure, anyone can become a monster to survive.
• Key Moments: The moment Sarah and Paul turn on Kim and Andrew, killing them in the woods, is the devastating apex of moral compromise.

8. The House as a Symbolic Safe Space—or Prison

Theory: Paul believes the family home is a fortress against outside evils, but it’s also an inescapable pressure cooker of mistrust and escalating paranoia.

• Why It Fits: The film rarely ventures beyond the house and its immediate surroundings, giving an oppressive sense that the characters are trapped. Walls designed to keep threats out also trap them with their own fears.
• Key Moments: Travis’s repeated nightmares often feature the house’s corridors—any perceived sanctuary is twisted into a suffocating labyrinth of fear and hopelessness.

Key Themes in ‘It Comes at Night’

Claustrophobic Tension and Isolation

The bulk of the story unfolds inside a single home, giving a sense of confinement that heightens every threat. Windows, locked doors, and the dense woods serve less as protection and more as barriers that trap everyone together under mounting pressure.

Nightmares and Uncertainty

Travis’s disturbing dreams blur the line between reality and paranoia. These moments aren’t just jump-scares; they reveal the film’s pervasive sense of uncertainty—no one knows what is truly real or imagined.

Erosion of Trust

When Will’s family arrives, trust initially offers hope. But as suspicions rise and rules tighten, human bonds crumble. The inability to communicate openly or believe one another propels the tension as much as any external threat.

The Weight of Responsibility

Paul and Sarah carry the burden of protecting their son, even if it means making grim choices. The film underscores how heavy that responsibility can become in a world where decisions are often life-or-death—and rarely clear-cut.

Fear of the Unknown

While a deadly virus is implied, its origins and scale remain ambiguous. This vacuum of information fuels a larger dread of “what might be out there.” By never showing a definitive monster or describing the world’s fate, the film turns the unknown into its own source of terror.

Moral Ambiguity in Survival

Survival instincts clash with compassion and ethics. The characters face impossible decisions—whether to risk aiding strangers or to protect themselves at all costs—spotlighting how morality can shift under extreme duress.

Plot Summary

• Year Released: 2017
• Director: Trey Edward Shults
• Writer: Trey Edward Shults

In It Comes at Night, Paul (Joel Edgerton), his wife Sarah, and their teenage son Travis live in seclusion to avoid a mysterious, deadly virus that has ravaged the world. Their strict quarantine is upended when Will, a desperate stranger, breaks into the house seeking supplies for his own family. Despite initial mistrust, Paul allows Will’s wife and son to move in, hoping cooperation will keep everyone safe.

Tensions rise as nighttime noises, strange occurrences, and Travis’s disturbing nightmares blur the line between paranoia and real danger. Suspicions erupt after the family dog turns up infected, fueling doubts over who might be carrying the virus—and whether the new arrivals can be trusted. A final, tragic confrontation ends in violence and the illness spreading within Paul’s household. By the film’s close, it is unclear whether the true threat lies outside in the woods or within the fearful, desperate minds of those struggling to survive.
