In a dystopian America devastated by war, environmental destruction, and political turmoil, the nation has transformed into a barren wasteland stripped of resources. Enter the Humanity Bureau, a merciless organization that enforces societal efficiency with brutal precision, sentencing those regarded as unproductive to the bleak confines of New Eden, where their fate is starkly grim. Noah Kross (Nicolas Cage), a resolute agent of this Bureau, is assigned to deport Chester Hills, a former governor of Colorado who now finds himself in despair. When asked why he chooses to remain in his dismal situation rather than escape to the supposed paradise of New Eden, Chester cryptically states that he holds "the truth." In a shocking turn, he lashes out at Kross and the hotel manager, leading to a violent confrontation that leaves Noah with no choice but to defend himself.
Kross's next mission takes him to assess Rachel Weller (Sarah Lind), a struggling single mother, and her young son Lucas (Jakob Davies). Despite their grim circumstances, they fiercely resist the Bureau's demands, clinging to their fragile existence. Sympathy grips Kross; he postpones his report to allow Lucas to showcase his talents at an upcoming music recital. This seemingly small act of rebellion ignites the Bureau's fury, drawing the ire of Kross's superior, Adam (Hugh Dillon), who begins to scrutinize Kross's decisions.
Rachel’s firm stance against the relocation and Chester’s enigmatic comments deepen Kross's curiosity about the elusive New Eden. A defense contractor working clandestinely for the Bureau hands him a memory card, further fueling his obsession with the truth about the mysterious city. The following day, Kross attends Lucas's recital, and, after sharing a meaningful evening with the family, finds his allegiance torn between his Bureau duties and his burgeoning sympathy for Rachel and Lucas.
The next morning, Kross awakens to a shock: Rachel is in Adam's clutches. In a daring act of bravery, Lucas, armed only with a BB gun, blinds Adam and helps facilitate their escape. As they flee from the pursuing Bureau agents, they find a brief refuge at a gas station, where Kross must confront the harsh reality of his invalid credit card and the bleak consequences he faces if they are caught.
In a desperate attempt to acquire gasoline, Kross holds the owner at gunpoint. Recognizing Kross's desperation, the owner selflessly crashes his truck into the Bureau vehicles, creating a diversion that allows Kross and the others to escape into uncertain territory.
Back at the Bureau, Adam faces severe repercussions for failing to capture Kross while the director unveils a chilling package: a child's tooth enveloped in dust, serving as a grim threat regarding Adam’s future in New Eden, where the Bureau eliminates those labeled as unproductive—a frank reminder of the terrifying thin line between efficiency and extermination.
Now determined to save Lucas and Rachel, Kross embarks on a perilous journey to uncover the hidden realities of New Eden. As their unmarked station wagon traverses the desolate landscape, Kross takes the reins of their fate, discarding the Bureau's vehicle for a shot at freedom. They encounter a mysterious figure who claims knowledge of a safer route north. However, this enigmatic guide warns of the dangerous radiation hazards that lie ahead—an ominous sign that no one who ventures forth ever returns.
Undaunted, Kross obtains a geiger counter and iodine pills from the man, along with a rabbit’s foot for good luck as they embark on this treacherous journey. As they navigate the hostile terrain, looming drones scan the area in search of Kross. Tensions rise between Kross and Rachel, culminating in a heated confrontation when Kross reveals his awareness of Rachel Weller’s true identity, exposing the harsh reality that the woman they've been traveling with is an imposter.
Flashbacks unravel a painful history: years ago, during a Bureau investigation, Kross had a personal connection with the real Rachel, leading to the birth of Lucas. When famine struck, desperation led Rachel to an unthinkable act - attempting to sell their child, a choice that ultimately cost her life when the neighbor Amanda discovered the plan. In a tragic twist, Amanda assumed Rachel's identity, raising Lucas while keeping Kross and the world oblivious to the truth.
As they navigate the dangerous terrain, the trio narrowly evades the Bureau's grasp, eventually arriving at a nuclear power plant falsely labeled as highly radioactive by their dubious guide. Yet, upon checking their geiger counter, they uncover the reality: it was merely a scare tactic to prevent refugees from seeking freedom.
Their harrowing journey culminates at the border where Agent Adam and his team confront Kross. In an unimaginable twist, Adam kills Rachel, demanding the memory card in exchange for her life. Kross reluctantly agrees to relinquish the card to save Lucas, only to discover its contents are nothing but empty footage.
As Adam executes Kross, Lucas makes a desperate escape, managing to flee from the devastation. The Canadian authorities quickly apprehend the Bureau agents, leaving Agent Porter as the sole survivor. In a tragic turn, Porter is ambushed and killed by a rebel on the road.
In the chaos that ensues, the true memory card is discovered hidden within the rabbit's foot, containing footage that exposes New Eden as a death camp, igniting widespread outrage against the Bureau. This revelation triggers a rebellion that plunges the nation into civil war, forcing Bureau personnel and their director to fight for their survival amidst the mounting chaos.
Ultimately, in a poignant finale, Lucas honors Kross by visiting the tranquil lake where his father once found peace through fishing—a powerful symbol of hope amidst the overwhelming wreckage of their world.
