Cooper, Christopher Rodriguez Marquette, is a classic office slacker who works as a telemarketer and drags himself into the workday late one too many times. His boss, Maureen Deborah Geffner, wastes no time reminding him that lateness and a talent for driving customers away have consequences, and she fires him on the spot. A thunderous, otherworldly crack shatters the moment, and Cooper collapses in a daze, waking days later nauseated and weak, cocooned inside the office walls.
When he finally breaks free, Cooper is met by a savage, beetle-like creature that attacks him as he struggles outward. He fights for his life and, in a desperate bid to save Maureen, frees her from her own confinement. Maureen regains consciousness and learns that her daughter Sara is outside, unconscious and trapped inside a cocoon-wrapped car. Together, the two fight through chaos, rescuing Sara as a cocooned threat closes in from all directions. But the danger multiplies: Maureen is captured by a large, wasp-like predator, and the others are swarmed by a growing chorus of bugs. The trio claws its way toward safety and escapes to a nearby restaurant, using quick thinking to buy time.
In the restaurant they stumble upon a ragtag rescue party—Cindy [Kinsey Packard], Hugo [E. Quincy Sloan], Hugo's father Albert [Wesley Thompson], Leechee [Linda Park], Roger [Bru Muller], and a cop [Todd Jensen]—who have all managed to avoid the worst of the infestation and are revived or revived-and-pushed forward. The group learns that the bugs are blind and hunt by sound, an astonishing flaw that becomes their best chance at survival. They stage a daring plan, using Sara’s car alarm to draw attention away from their movements and to slip past the nightmarish swarm. The discovery of a hive in the distance and the looming red gas that plants the nest’s ominous glow adds a new layer of urgency to their escape.
Leechee analyzes the bugs’ venom after the group captures a specimen, revealing a mixture of sedatives and proteins that could hold the key to stopping the attack. Armed with this information, they decide to push toward the nearest military airbase for help, with the nucleus of the group rallying around the idea that a larger defense could turn the tide. They catch glimpses of the red-hued gas nest emitting a toxic fog, fortifying their sense of mission. Leechee remains behind, devoted to reviving more people and studying the bugs—her sacrifice underscoring a quiet, scientific resolve amidst catastrophe.
Their next stop is Hugo’s house, then Chad’s residence, where Cindy’s family spirals into further peril. Albert’s wife is found, the remnants of normal life breaking under pressure, and Cindy’s sister Susan cocooned and revived. Chad, now mutated into a large, spider-like creature that collects cocooned humans, attacks the group, killing Susan, knocking Sara temporarily unconscious, and impaling Cooper as he attempts to save Cindy. The fight ends with Chad’s brutal defeat at the hands of Hugo and Albert, a moment that strains loyalties and raises the stakes for everyone.
The night is spent regrouping, with Sara patching up Cooper and the group weighing their next move. Cindy tries to persuade Cooper to join her, but he is resolute—his feelings for Sara keeping him tied to the mission and to the fragile bond they share. The following day they press toward Cooper’s father, Ethan [Ray Wise], a veteran who maintains a bunker and a cache of weapons. Sara voices a wish to reach the hive to search for her mother, and Cooper attempts to dissuade her, sensing the danger yet feeling a duty to help. The trip becomes a tense chase, crossing under a bridge to evade patrols of flying bugs. Cindy’s actions—revealed jealousy over Cooper and Sara by exposing their closeness—backfire when her alarm draws a cluster of insects toward the group. Albert acts quickly and shoots Cindy to protect the others, but the loss underscores the brutal stakes of their journey. Sara is captured again as the group moves on, the hive drawing nearer with each step.
At Ethan’s house, the tension spikes as Albert mutates into a further distortion of the earlier creature, and Hugo is forced to shoot his own father in defense of the group. Cooper presses Ethan for help to rescue Sara, but Ethan refuses, and Cooper and Hugo find themselves captured by another faction that holds them in a ruined, abandoned police station. There, a Puerto Rican man—another survivor who speaks of Leechee’s group—explains that the nest’s red gas caused a catastrophic explosion. The man himself mutates into a fearsome creature, providing a disturbing reminder that even survival has a high price in this world. Even with the chaos around them, Ethan uses the distraction to eliminate the hostile group and free Cooper and Hugo.
Meanwhile, Sara awakens inside the bug hive and comes face to face with the queen as she devours cocooned humans. The trio—Ethan, Hugo, and Cooper—make their way into the hive, with Ethan binding Cooper to a tree and venturing inside alone to confront the heart of the threat. Sara offers to guide him to the queen; they are ambushed, but Hugo and Cooper rush to aid them. The queen’s ear-splitting wail of rage intensifies the danger, a sound that even Hugo, who has lost his ability to hear, cannot ignore too long. He hurls explosives into the queen’s mouth, a desperate act that creates a rift in the hive’s defenses.
Ethan orders Sara and the others to escape as he triggers a final, devastating blast. In a grim twist, he himself mutates again in the moment of sacrifice, and Cooper seizes the remote from his father to finish the destruction of the nest from the outside. The blast obliterates the hive and the insects within, leaving only smoke and a heavy, tense silence in its wake.
The film ends with the remaining trio—Cooper, Sara, and Hugo—turning toward the distant, ominous rumbling that promises the aftermath will be far from over. The odds are astronomical, yet they press forward, gripping each other’s hands and bracing for whatever comes next in a world where tiny sounds can decide who lives and who dies. >“The noise is our ally now.”<
