Adam Goldstein [Gabriel Basso] wakes in a barricaded cabin, infected with an unknown virus that mutates his body and leaves him with no immediate memory of who he is or what has happened. The walls feel suffocating, the night is full of strange noises, and a voice in his head seems to echo the hive mind that may control what’s happening outside. Through a careful weave of flashbacks, self-written messages, and a trail of sketches and photographs tucked away like clues, Adam gradually reconstructs a past that feels ripped from a nightmare and yet somehow real.
In the shadows of the past, a cold, scientific thread unfolds. In the 1980s, Dr. Yuri Yegorov [Ilya Baskin] conducts experiments aimed at linking brains into a single hive mind. The procedure, though alluring in its promise, spirals quickly: the subjects mutate, break their restraints, and lash out with deadly force, turning what should be a breakthrough into a terrifying danger. The lab atmosphere crackles with danger as the hive concept starts to reveal its dark side, and the ethical lines blur under the pressure of ambition. As scientists push forward, a separate strand of memory hints at a darker chapter—Dr. Baker’s work and a young patient named Kayla [Talitha Eliana Bateman], who speaks a complex equation before she dies during a delicate operation. The image of Kayla’s recitation becomes a haunting motif that drives Dr. Baker in his pursuit of funding for research into shared memories, a pursuit that attracts a shadowy male figure who arranges a laboratory setup built on Yegorov’s findings. Yet Yuri Yegorov’s own warnings grow louder: the deeper they go, the more perilous the experiment becomes. When Baker refuses to step back, Yegorov grabs the upper hand, holding him at gunpoint while accomplices steal the hive virus samples. The stolen material surges into motion as a hijacked plane carries the threat away to an uncertain fate.
Back in the present, Adam’s mind drifts to his old life at Camp Yellow Jacket, where he served as a counselor alongside his friend Clark [Jacob Zachar]. The memories are tangled: flings and flirtations, a secret dalliance with a fellow camper Jess [Gabrielle Walsh], and the steady pull of a romance with a girl named Katie [ Kathryn Prescott]. The camp’s close quarters and the sense of belonging it offered feel both comforting and dangerous in the same breath, a precursor to the kind of bonds that memory and fear alike can distort. The past surfaces with a raw honesty as Adam relives the night they all confronted a danger that was bigger than any one of them—a danger that would soon surface again in a form even more intimate and insidious.
A violent turn of events follows: Yegorov’s plane crashes in a nearby forest, and Adam, Clark, Katie, and Jess converge on the wreckage to investigate. They are immediately ambushed by the infected, a horror that forces them to retreat on foot back to the camp. The infected arrive with a ravenous intensity, and one unsettling detail echoes through the night—the pilot vomits a black substance that appears to spread the infection to those it touches, sealing Jess’s fate in a brutal moment that drives home the severity of the outbreak. The survivors scramble to safety, but the danger is far from over. The immediate threat shifts into a battle of wits against an unseen, collective force that has begun to blur the lines between individuals and a larger, shared consciousness.
As the infection tightens its grip, Adam and Katie attempt to keep Clark and Jess safe, moving through the camp’s dim corridors to radio for help. The plan falters when Adam discovers the full scope of the contagion among the camp’s children, forcing them to separate and improvise. Adam leaves Katie alone in a vehicle as he presses ahead to map the scope of the outbreak, hoping to find a way to help everyone else escape. In a chilling revelation, Jess communicates through hive mind channels to reveal her own past with Adam, exposing intimate truths that turn friendships into fragile lines of trust and betrayal. The revelation shatters Clark’s resolve, and he lunges to confront Adam, who is ultimately forced to defend himself.
The infection’s grip tightens as Katie returns to the infirmary, now bearing the burden of possession. Adam, hoping to escape with her, tries to save himself by letting her know what she is up against. Jess makes one final, desperate attack, leaving Adam with a brutal choice: kill Jess to survive or become overwhelmed by the hive’s pull. The brutal necessity of self-preservation becomes a grim, defining moment. Adam’s actions show a man who loves Katie enough to fight for her consciousness, even as the hive mind gnaws at the edges of his own. He locks Katie in a separate room to shield her from the growing contagion, yet the virus proves stubborn, infecting him in turn.
What follows is a meticulous, almost ritual attempt to defy the hive mind’s grip. Adam leaves a series of messages and clues for himself, explaining the impossibly complex situation in a way that might guide him through the inevitable possession he senses is coming. He leans on a memory of his feelings for Katie as a trigger to keep himself anchored long enough to fight back, and he even employs a soldier’s memory and a defibrillator to restart Katie’s heart when she appears to die. Katie returns to life, regaining some measure of control over her own sentience, and the two of them slip away from the cabin, hoping to outrun the encroaching nightmare.
Their flight is a perilous escape through a world increasingly overrun by the infection, and the two lovers battle through a landscape that has become a battleground between autonomy and annihilation. In the end, their escape seems almost miraculous, but Adam’s narration carries a chilling caveat: he has planted false memories of their escape to shield Katie from a cruel truth he cannot bear to deliver. The world they leave behind is not the world they found—the hive mind’s reach appears to extend far beyond the cabin, and the knowledge that he might be shaping her memory to protect her suggests a grim, unresolved fate for both of them.
The tale unfolds with a restrained, steady tempo that keeps the focus on memory and choice amid a fearsome, fracturing reality. The tone remains measured and clear, never surrendering to melodrama even as it confronts questions about memory, identity, and the consequences of scientific ambition. The film ultimately asks whether love and loyalty can endure when the mind itself becomes a battlefield, and whether the human heart can still choose truth when every memory might be a carefully crafted illusion.
