What Is Impulse About?
The premise of Impulse in 274 words, with nothing given away. The full story follows below.
In an isolated town where the quiet is as palpable as the surrounding fields, a low‑magnitude earthquake becomes the catalyst for something unseen to stir beneath the surface. The tremor awakens the hidden cravings and restless urges that the residents have kept locked away, turning everyday routines into unsettling displays of raw, irrational behavior. The atmosphere cracks open like the fissures in the earth, allowing a blend of dread and fascination to seep into every street, shop, and farmhouse, setting a tone that is simultaneously intimate and menacing.
Into this fragile community arrive Stuart, a pragmatic visitor whose curiosity leads him to sample the locally produced milk, and his girlfriend Jennifer Russell, who instinctively holds back. Their journey begins as a simple trip to see Jennifer’s ailing mother, but the town’s strange undercurrents quickly press against their relationship, hinting at deeper questions about control, desire, and the thin veneer of civilization. The contrast between Stuart’s willingness to partake in the town’s familiar comforts and Jennifer’s cautious abstention creates a subtle tension that mirrors the broader unease spreading through the populace.
The town itself feels like a character—its modest homes, the lingering scent of dairy, and the ever‑present hum of an uneasy stillness—all amplified by the recent quake. As the residents’ suppressed impulses surface, ordinary interactions take on a fevered intensity, suggesting that something far more potent than the tremor itself is at work. This uneasy blend of psychological thriller and atmospheric horror invites viewers to wonder what truly lies beneath the surface of a seemingly placid community and how easily a single event can unleash the chaos that has always waited in the shadows.

Spoilers ahead
Stuart, Tim Matheson, and his girlfriend Jennifer Russell, Meg Tilly, come to the town to visit her hospitalized mother. From the moment they arrive, a creeping unease settles over the place as several residents display increasingly odd behavior. While Stuart drinks the local milk, Jennifer abstains, and the day slowly spirals from curious oddities into something far more disturbing as the townspeople and Stuart begin to show signs of violence and extreme sexuality.
Jennifer visits her friend Margo, Amy Stryker, and discovers evidence that Margo’s son Jimmy has suffered a serious injury to his arm. When Jennifer tries to leave in her car, she finds her tires slashed by Jimmy and Shawn, trapping her in a cycle of escalating danger. If she escapes in Margo’s car, Jimmy and Shawn chase and trap her in the garage, setting it on fire. She barely makes it out alive as the fire closes in around her.
The town’s strain deepens as the local physician, Dr. Carr, Hume Cronyn, euthanizes Margaret and then takes his own life. The shock of these events ripples through the community and into Jennifer’s circle, especially when Stuart learns that Jennifer’s brother Eddie, Bill Paxton, harbors incestuous feelings for her and kills him, intensifying the sense that something has corrupted the town from within.
As chaos takes hold, Jennifer flees in a pickup, only to be stranded outside the town. Meanwhile, Stuart hides in the woods and uncovers a recently repaired toxic waste vault that leaks into a vat of milk, a discovery that ties the outbreak to a deliberate contamination. He follows the conduit back toward town, and fate puts him face to face with Jennifer in the stranded vehicle; he frees the truck and urges her to leave, explaining that she is the only uninfected person who can escape, even as he vows to return and help as best he can.
Two men are seen loading a biplane with barrels of liquid, and after the plane takes off, a government vehicle filled with radios reveals plans to spray the town. When Stuart confronts the man, the orderly exchange ends with him being shot. Jennifer, who had started back toward town, witnesses her boyfriend struck down, and she drives down the assailant, killing him in a desperate act of self-preservation.
The town sits in a grim tableau: roads and streets are littered with corpses, and a news report notes that government agencies have no explanation for the mass death that has befallen the town. Jennifer walks away as the sun sets, moving forward into an unsure future, the weight of the night still heavy on her shoulders.

Contagion
A mysterious contamination transmissible through the town’s milk and environment drives the plot.

Characters struggle to identify the source while trying to protect themselves and loved ones.
-
02
Conspiracy
Evidence suggests an external influence: a government-linked figure, radios, and a plan to spray the town. With authorities offering no explanation, paranoia and suspicion permeate every interaction. The narrative toys with the idea that power behind the scenes orchestrates the town’s downfall.
-
03
Chaos
As fear overrides restraint, societal norms collapse and violence erupts. The protagonist and others must navigate a landscape where trust is scarce and survival hinges on impulse rather than principle. The town’s institutions fail to contain the outbreak of hostility.
