Dexy, Diva, a sexually adventurous woman, presses her husband Nathan to find her “someone to play with” as the world outside crumbles. In the opening shock of the movie, a man armed with a one-handed sledgehammer and long spikes battles a zombie in raw, visceral fashion and triumphs by driving a spike straight into the creature’s skull. The nameless killer is revealed to be Matool, Kurly Tlapoyawa, whose cool competence and brutal toolkit instantly mark him as a force to be reckoned with. He doesn’t just survive—he operates with a kind of grim efficiency that stands out in a city emptied of life, where the streets of Albuquerque flicker in montage as the pair’s separate paths collide with the collapse of civilization.
A desperate beacon pulls Matool toward a trapped young woman outside, her vehicle hemmed in by ravenous zombies. He sprints to her aid, shouts a defiant expletive, and carries her to safety into a dilapidated house. Inside, they find a small, uneasy shelter: Mr. Rainville, a quiet, unconcerned elder, and two young boys who observe the chaos with a mix of fear and detachment. The woman reveals that the slain man was her brother, a fact that excites Matool but also sparks tension, as she clings to the hope of saving him in death. Rainville, uninterested in moralizing, offers wry one-liners about not joining the party of sex or death, while the more outspoken younger child watches the world fall apart with a strange, silent gaze.
The shelter becomes a stage for new dynamics. Dexy’s visitors and the house’s occupants explore boundaries and power, with Dexy’s allure shaping the room even as the family’s secrets come to light. Dexy’s sister, Sassy, introduces a tang of danger and sharp wit, and the group learns there’s more going on than simple survival. Dexy’s allure draws in more than just attention; a “mutated” companion on Sassy’s side—a face that seems almost self-aware on her own body—becomes a focal point of fascination and discomfort for Matool, who watches the evolving family drama with growing curiosity. The subtle, charged conflicts between Matool, Dexy, and the others begin to surface as they navigate threats outside and the fragile bonds inside.
A small, brutal sub‑plot unfolds within the house as a group of soldiers—led by Mandel, Billy Garberina, and accompanied by Vega, Devin O'Leary—arrives in the rain and stakes a claim on shelter and supplies. Wounded Sepulveda, their companion, is kept under watch, a reminder that every choice now carries the weight of life or death. The flashbacks reveal a harsh backstory: the road warriors survived by moving from one ruined outpost to another after a flood of hyperzombies—faster, more dangerous creatures—tore through the landscape. The new arrivals discover the mountain home is stocked with power, a well, and “more,” drawing a fragile line between safety and temptation.
As days pass, Vega and Sassy form a tentative bond, while Sepulveda’s agony slowly becomes a drumbeat of mortality. Mandel and Matool bond over shared struggles against the undead, and Nathan’s presence is felt even when he is not on screen—Dexy and the others still attempt to adapt to their own unconventional arrangements, with Dexy and Nathan’s arrangement reflecting deeper themes of autonomy, desire, and control. A disturbing incident emerges when Matool notices a naked zombie—one of Nathan’s private curiosities—locked in a shed behind the house, a macabre display that blurs the line between monstrosity and humanity.
The situation grows darker as the quiet boy—who has not spoken a single word since the onset of chaos—begins to react to Dexy in a new, unsettling way. He steals the keys to the house, frees the chained zombie, and creates a new kind of danger within the shelter. The tension comes to a head when Sepulveda awakens and witnesses Sassy with her conjoined twin on her side, a grotesque image that shocks him to the core. In a moment of panic, Sassy stabs him with scissors, and Mandel, reacting to the rising chaos, shoots Sassy to protect the fragile equilibrium of the house. Dexy’s world becomes more dangerous as Nathan’s zombie companion devours him, a brutal reminder that the living and the dead share the same fragile thread.
Matool, Mandel, and Vega remove the bodies of Sepulveda and Sassy before they reanimate, attempting to preserve some sense of order in the face of catastrophe. They drag their fallen comrades into the shed and try to reassure Dexy that the losses are accidents of war rather than intentional acts. But the siege outside grows louder as more zombies converge on the home, and the trio finds themselves cornered. A moment of raw disbelief follows when Dexy’s fragile sense of normalcy is shattered by the realization that their safety may not be guaranteed and that human loyalties have shifted in unpredictable ways. The group fights their way through the siege, with Mandel landing a critical blow against Matool, claiming Dexy as his own—but Matool counters with stubborn resolve and fierce determination to survive alongside Dexy.
As the encroaching horde closes in, the trio discovers the full scale of the danger, and the house becomes a trap from which escape requires extraordinary resolve. Nathan’s zombie companion gnaws at the shed door, and the remaining men are forced to abandon their fragile alliance and run for their lives along a muddy gravel road.
In the final, harrowing beat, Dexy watches the world descend further into chaos while the boy—a silent fixture of the house—approaches her with a quiet finality. He gently takes Dexy’s hand, offering a glimmer of human connection amid a landscape overrun by the dead. Dexy’s line, delivered with weary resolve, seals the moment: “Nathan will be back,” a line that lingers as the road stretches before them. Matool and Mandel push forward on that same road, united by a shared determination to survive in a world where protection, desire, and loyalty must be renegotiated with every new sunrise.
