A Tuesday evening KRKY 97 broadcast establishes the situation in Colorado: new curfews and mandatory travel checkpoints are in effect, record heat continues, and fire danger is high across the mountains.

At a Millerville public pool after swim practice, 12-year-old Ashanti Johnson—who habitually frames everyday life through Greek mythology—waits while her mother finishes reading. Ashanti asks permission to sleep over at her friend Emma’s house on Friday; after a thorough round of parental questions, her mother agrees.

Ashanti texts her friends Emma and Maddie that the weekend sleepover plan is confirmed.

Starting at 2:30 am Wednesday on a ranch near Feathermore, 14-year-old Grandin Stone helps his parents assist a weakened mother cow through a difficult labor. Grandin and his dad pull the calf free and clear its airway. The calf survives, but the dehydrated, exhausted mother cow dies. His dad mutters that “ranching gets harder / every year” (14).

That Wednesday afternoon, 12-year-old Harmony Addams-Paul writes to her Aunt Beckie, an international journalist. She describes her journalism class with teacher Mr. Sedillo, who encourages her to observe both herself and the world around her with journalistic attention. She is excited to have received her own press badge, and she plans to use these letters as practice in observation and reporting.

Harmony’s school journalism assignment describes how she and her little sister, Pax, make a Mother’s Day gift in their Redhawk apartment—gluing an upside-down flowerpot to its saucer to form a chalice, the symbol of their mother’s church. Harmony notes that it is the first Mother’s Day since her parents’ divorce.

On Wednesday evening at the Alpenglow Dinner Theater in Spruce, Colorado, 11-year-old Teddy Brenkert—a serious, film-obsessed aspiring filmmaker—delivers a glucose monitor to his grandmother, called Gram, as she works the ticket counter. He then returns to the tech booth to film the second act of a production of The Wizard of Oz. After the show, Teddy complains that the actor playing the Tin Man consistently misses his lighting mark, ruining the footage. On the drive home, Gram notes that their local talent pool is limited. Teddy mutters that he wishes he could go straight to film school, to work with people who take art as seriously as he does.

Thursday’s KRKY 97 broadcast reports National Guard convoy delays on certain roads and announces that Governor Clark will hold a press conference the next day to introduce drought management measures, including new restrictions on urban and agricultural water use.

Grandin’s dad switches off the broadcast, dismissing government involvement in ranching and lamenting that politicians no longer serve in the military, where he believes they would learn the proper values. Grandin’s Ma quiets him for dinner. Privately, Grandin resolves that when he enlists, he will protect the land and its resources and restore his father’s faith in the future.

Ashanti reveals that she has lied to her parents for the first time. She, Emma, and Maddie have each told their parents they will be staying at one of the others’ homes, while all three actually plan an unsupervised night at Maddie’s grandparents’ empty apartment.

Late Thursday night, Harmony prepares a report about influential journalists, including Ida B. Wells, Ida M. Tarbell, and Upton Sinclair. She watches military convoys pass her apartment, furious that her mother is out past curfew. When her mother finally returns, she explains that a dying parishioner needed her to administer last rites. Harmony worries about what would happen to her and her younger sister, Pax, if something happened to their mother. Another truck shakes the building as she goes to bed.

Just before midnight, a state trooper pulls over Gram and Teddy for violating curfew. Gram presents their dinner theater employment passes and is allowed to proceed. When Gram questions whether the curfew is necessary, the trooper states that additional safety measures are justified.

Early Friday morning, Grandin bottle-feeds the orphaned calf, which failed to graft onto another cow, first coaxing it to drink by sweetening its mouth with honey. His dad enters, watches, and gives a silent thumbs-up. Grandin turns away to conceal his pride.

Mr. Sedillo praises Harmony’s oral report on muckraking journalists but criticizes her for yawning. She quietly blames her mother’s late return the previous night. She vows to stay fully engaged, citing Gilded-Age investigative journalist Nellie Bly’s belief that focused effort can achieve results.

Friday afternoon, Gram finds Teddy editing theater footage after finishing his online schoolwork. She presses him about making friends; he deflects and shows her how he plans to fix a performer’s flubbed lyric using audio from another night. When she insists he stop for lunch, he agrees, then immediately turns back to his screen, where Dorothy and the Scarecrow are frozen amid dancing and singing.

Friday evening, Ashanti comes down with fever and stomach flu. She frames this as divine retribution for deceiving her parents. The secret sleepover is canceled.

Late Friday night, Harmony wakes and finds her mother watching a military Humvee idling in the street. Her mother tries to reassure her. A second Humvee parks at the end of the block. Harmony associates her mother’s dismissive reassurances with the evasions of her parents’ divorce and feels sudden fear.

At 12:01 am Saturday, a mass emergency alert declares an imminent threat and instructs all residents to follow local authorities, emphasizing that this is not a drill.

A Colorado National Guard Reverse 911 message orders mandatory evacuations and directs all residents to proceed immediately to designated embarkation zones.

KRKY 97 reports live mass evacuations across Colorado. The cause is officially unknown, though unconfirmed reports suggest one or more pipeline explosions; terrorism has not been ruled out.

After hearing strange noises at night, Grandin’s dad outside, armed with a shotgun, to investigate. He finds a deputy sheriff ordering immediate mandatory evacuation. He argues and refuses to comply while Grandin watches helplessly.

Harmony’s mother wakes her and Pax to evacuate. Harmony grabs clothes, books, her notebook, and her press badge. When Pax wants to bring the homemade chalice, Harmony says no, promising they will be home by Mother’s Day.

Still feverish and disoriented, Ashanti is woken by her mother and her father, whom she calls Pop. They help her dress and load the car with suitcases and her mother’s medical bag before driving off.

Stopped at a military checkpoint, Gram and Teddy are directed to the train station in Ute Junction. The soldier confirms an imminent threat but declines to explain the cause. Teddy begins filming as they drive on.

The Stone family follows the deputy’s car toward Timberline, forbidden from bringing trailers or livestock. Grandin worries about the animals left behind. His father seethes; his mother twists her wedding ring. No one speaks.

With traffic gridlocked twenty blocks from the Ute Junction train station, Gram decides to abandon the car and walk. Teddy runs back at the last moment to retrieve her glucose monitor, then catches up and jokingly tells her they are off to see the Wizard.

At the packed Redhawk fairgrounds, Harmony carries Pax piggyback to keep her safe in the dense crowd. She notices her mother wearing her clerical collar, which she says can be useful for gaining access, and wonders anxiously what door she fears will remain closed.

From a park-and-ride embarkation point, Ashanti texts Emma and Maddie that she is running a 101-degree fever and scared, and that the family is in line for bus number 78, which may be full.

Outside the Ute Junction train station, a recorded announcement orders all evacuees to surrender cell phones, which have allegedly been compromised. After spotting soldiers wearing gas masks, Gram decides to comply and drops both their phones in a collection barrel.

Before boarding school buses, evacuees must reduce their belongings to a single bag. Harmony’s mother leaves behind extra clothing; Harmony discards a jacket from her father. On the bus, Harmony writes to Aunt Beckie, vowing to document events for her school paper, the Bulldog Bulletin, and to stay awake.

On the bus, Ashanti’s Pop gives her water while her mother urges hydration. Still feverish, Ashanti falls into a restless, monster-filled sleep.

On a packed train heading east, Teddy attempts to interview Gram on camera, but she is too tired and asks him to stop. He drapes his sweatshirt over her as she sleeps and takes out a notebook to write.

In his film production diary, Teddy debates the format for a documentary about the evacuation, settles on the working title “Imminent Threat,” writes a brief premise, sketches a storyboard, and notes practical concerns about battery power and storage.

At the Timberline Regional Airport embarkation point, Grandin’s dad refuses to surrender his phone; two soldiers forcibly take it. He then resists boarding the military personnel carrier set to take the family to the evacuation shelter. As Ma and Grandin board the carrier, Grandin looks back and finds that his father has vanished from the crowd. Ma whispers for him to let his father go, as someone needs to care for the livestock. Trapped in the press of bodies, Grandin is terrified and unable to move.

A news broadcast confirms historic mandatory evacuations across Colorado and reads a statement from the Incident Command Center at Camp Rogers pledging to protect state infrastructure and ensure the safety of all residents.

On a school bus traveling through eastern Colorado, Harmony’s mother wakes her and Pax with breakfast. Pax, prone to motion sickness, refuses to eat.

Ashanti wakes on the bus soaked in sweat but feeling better; her mother confirms that the fever has broken and gives her juice. Ashanti mutters a mythological warning never to eat or drink in the underworld, but her mother reminds her that she is not a mythical god or hero but a real person who needs to stay hydrated.

After a long ride in the personnel carrier, buildings appear in the distance, and the truck slows. Grandin’s pulse quickens as they approach their destination.

The evacuees arrive at Camp Rogers, a large former military base with a Disaster Assistance Center. While Teddy holds their place in line, Gram grows unsteady, so he sends her to a bench with a butterscotch candy. Filming the crowd, he notices a girl holding a notebook—Harmony—staring at him with intense focus before she disappears.

On their second day at Camp Rogers, Harmony writes to Aunt Beckie, describing the base as a former Cold War installation. Her mother has gone to volunteer. Pax is excited about a white squirrel she spotted on the quad. Harmony has not seen any of her friends and learns that evacuees may have been distributed across multiple centers. In the mess hall, she spots the boy who was filming outside and wonders if he is a fellow journalist.

At breakfast, Grandin has no appetite and finds the mess hall food bland. He watches his mother stir coffee she never drinks and stops himself from asking whether his father made it out safely.

Putting on her press badge, Harmony attempts to interview Pax as her first subject. Pax refuses, insisting on playing Dorothy from The Wizard of Oz instead. Harmony grows frustrated with her uncooperative subject.

Teddy introduces himself to Harmony and Pax. He explains that he is making a documentary about the evacuation; Harmony says she is covering it for her school paper. Pax draws Teddy into her Wizard of Oz game—he claims the role of the Tin Man, and Pax assigns Harmony the Scarecrow. When Harmony invites Teddy to help conduct interviews, he enthusiastically agrees and rushes to get his camera. Pax jokes that they are far from Kansas now.

Grandin and his mother spend the day in slow-moving lines for supplies and paperwork but receive no information about the threat or when they may go home. He worries about his father and finds the memory of the moment his father vanished already beginning to blur.

Because Dr. Johnson is a physician, Ashanti and her parents are directed to a separate line. Ashanti assumes her mother will set up an infirmary in keeping with her oath. She reflects that when she becomes a doctor herself, she will find a cure for the stomach flu.

General Giles of the Colorado National Guard tells reporters that the state had monitored credible threats for months before Friday’s intelligence triggered Operation Relocate Freedom. She cannot identify the specific danger or name those responsible. When asked about the confiscated phones, she explains that a cyber team determined all devices had been covertly compromised; all cell towers, internet providers, and power in evacuated zones are being shut down. The press conference ends abruptly when an officer calls the general away on an urgent matter, leaving reporters’ questions unanswered.

Grandin is deeply frustrated by the press conference’s lack of concrete answers. Three questions dominate his thoughts: what danger justifies the evacuation, when can they go home, and where is his father? His mother urges patience, but Grandin is overwhelmed with worry.

While her mother sets up a clinic, Ashanti—still drained from the flu—longs for her own bed. The past three days feel barely real.

While Pax plays near her mother’s volunteer station, Teddy and Harmony conduct interviews—Harmony asking questions, Teddy filming from multiple angles.

Harmony writes to Aunt Beckie reporting that Red Cross landlines have five-hour wait times and that her mother refuses to call her father for help. After days of joint interviews with Teddy, she has collected wildly contradictory rumors: a chemical spill, broken dam, pipeline burst, alien colonization, and nuclear accident. She concludes that no one actually knows what is happening.

Harmony’s article profiles twins Elliott and James Davis, who cannot reach a stepsister sent to a different location; a tall boy in cowboy boots—apparently Grandin—who refuses to be interviewed and seems to be searching for someone; and seventh grader Ashanti Johnson of Millerville, who was evacuated while ill with the stomach flu.

In his film diary, Teddy notes that he feels calm while others panic. He enjoys collaborating with Harmony—their styles different but compatible. He debates whether the film should document the evacuation experience or investigate its unknown cause, and he makes a personal note to monitor Gram’s medication supply.

Three weeks after the evacuation, an Incident Command advisory posted in the Disaster Assistance Center (DAC) states that toxic synthetic chemicals, lethal to humans and imperceptible, have been found in the evacuation zones. The evacuation zones are expanding, and all evacuees must remain under indefinite lockdown.

Harmony writes that the camp is now fully sealed: Landlines have been removed, and military police have arrested evacuees caught with hidden phones. She describes a recurring nightmare about being suffocated by a living fog and admits that an imperceptible poison frightens her more than any visible disaster.

Grandin fears that his father cannot detect the invisible toxins and may already be in danger. His mother tries to hold on to hope, saying his father is likely in a safe area, but her eyes reveal she believes otherwise. Grandin feels paralyzed.

Teddy brings Gram to the camp infirmary. While waiting, he meets Ashanti, who keeps him company with lollipops as he worries about Gram’s dizziness and insomnia. Dr. Johnson reports that Gram’s symptoms stem from anxiety, not illness, and gives her breathing exercises. When Dr. Johnson asks how Teddy is holding up, Ashanti jokes that everyone at camp is FINE—Freaked Out, Insecure, Nervous, and Exhausted. Teddy denies the first two.

Since the contamination announcement, the infirmary has been flooded with patients reporting aches, blurred vision, and dizziness, all convinced they have been poisoned. Dr. Johnson finds no clinical evidence of toxicity in any of them and explains that not all exposures constitute poisoning. Ashanti concludes that her mother believes these patients have been sickened by fear alone.
