While journeying on foot, a woman grapples for survival as a slow-moving zombie relentlessly
chases her.
During a zombie outbreak, Molly and Nick, a couple from Las Vegas, escape from the city
to join a friend at a secluded airfield to leave the country.
On their journey, the intoxicated woman urges the driver to pull over so she can throw up
by the roadside.
However, when she returns to the car, they discover they cannot continue their trip because
the vehicle is stuck in the sand.
To contact their friend, Jimmy, Nick steps away to get a phone signal.
While he successfully makes a call, their conversation is frequently interrupted due
to the poor reception.
Suddenly, Molly grabs his attention, gesturing towards a man approaching them.
However, as the stranger draws nearer, they quickly realize he is a zombie.
In a state of panic, Nick hastily dashes into his car to retrieve his handgun, accidentally
dropping his phone.
He fires his weapon, putting down the undead man, which leads to a celebratory moment with
his girlfriend.
However, it doesn't take long for Molly to observe that the zombie is beginning to recover.
As the horrifying creature advances towards them, Nick shoots at it again, but he runs
out of ammunition, prompting the couple to secure themselves inside the car.
While huddled inside the vehicle, the woman considers seeking help through Nick's phone,
but he admits he dropped it.
The man then tries to comfort his girlfriend by saying that the zombie will eventually
lose interest in them.
However, hours pass, and the couple remains trapped inside as the undead man persistently
pounds on the car window, leading to an argument between them.
After they finish arguing, Molly suddenly realizes that the zombie has disappeared.
They turn on the high beams and use a flashlight to search the area, but the undead man is
nowhere in sight.
Believing the zombie has moved on, the couple exits the car to look for the phone.
However, as Molly finally retrieves the device, she is met with the horrifying sight of the
undead man attacking her boyfriend.
As the zombie devours Nick, Molly swiftly reenters the vehicle and gathers her supplies
into a bag.
When she realizes the undead man has disappeared, she uses her flashlight to search but finds
no trace of him.
Continuing to pack, she suddenly notices the zombie behind her, prompting her to kick him.
Terrified, she scrambles to exit the vehicle through the passenger-side door, clutching
a flashlight, Nick's phone, and her backpack, and runs towards the desert.
Having distanced herself from danger, Molly stops and sits on the sandy ground, sobbing
due to panic and fear.
The following day, she finally gets a phone signal, leading her to call Jimmy.
Instead of revealing the truth about her boyfriend's demise, she asks their friend to wait for
them the next day at the airfield, attributing their delay to "car trouble."
However, Jimmy hints that he can't make any promises.
Following the call, Molly assesses her remaining supplies and embarks on a solitary journey.
When she spots aircraft flying above her, she attempts to grab their attention, but
they continue past her.
As the sun sets, the lone survivor kindles a bonfire.
Exhausted, she shuts her eyes and recalls cradling her son.
Suddenly, the zombie appears and attacks her.
She defends herself by grabbing his neck and pushing him away.
Exhausted, she runs off, leaving her supplies behind, and rests on a rock formation.
The next day, Molly wakes up to find the zombie attempting to reach her.
The survivor moves around and notices that the undead man can't climb.
Soon after, she devises a plan to lure him away.
She throws a stick and instructs the zombie to fetch it.
When her initial plan fails, the woman attempts to use her used tampon as a lure, which elicits
a response from the undead man.
She tosses it away, causing the desperate zombie to chase after it.
While the undead man is preoccupied, Molly descends from the rock formation but has a
fall.
Her cry of pain catches the zombie's attention, prompting her to hurry and retrieve her supplies.
Afterward, Molly walks briskly while the slow-moving zombie follows behind.
Before sunset, she stumbles upon an abandoned desert house.
Upon entering, she discovers the cupboards are empty.
Seeing a bed, she lies down and reminisces about the times she and her husband lay together,
awakened by their son.
Upon hearing an unfamiliar noise, she awakens to find the zombie inside the house.
Panicked, she hides in the bathtub, where she remains unnoticed, even though the undead
man is just behind the shower curtain.
Suddenly, a scorpion crawls over her, causing her to stifle her panic.
Once the zombie departs, she picks up the arachnid, tosses it to the side of the tub,
and ends its life by crushing it with her shoe.
When the coast is clear, Molly departs from the abandoned house and resumes her journey.
However, as she finds a place to rest, the zombie suddenly appears from a distance, steadily
advancing toward her.
As the undead man draws nearer, the woman pelts him with stones and eventually flees,
haunted by the memory of how the zombie had taken Nick's life.
While the zombie continues to pursue her, Molly keeps a safe distance and urges the
horrifying creature to keep his mouth shut due to the irritating sounds he emits.
Growing annoyed and frustrated, she mocks the zombie, likening him to a used car salesman
because of his attire, and speculates that he must come from a dysfunctional family.
In a moment of dark humor, she gives him the nickname "Smalls," assuming that the undead
man has a tiny private part.
That evening, she arranges a bonfire and suddenly reminisces about her previous job as an exotic
dancer.
While she drinks liquor, the zombie stands across from her, observing intently.
The following day, Molly pretends to be Nick and contacts Jimmy.
The individual on the other end of the line explains that they encountered car trouble
and urges the couple to meet him at the airfield the following day.
However, he sternly warns that if Molly and Nick fail to arrive on time, they'll leave
without them.
While walking, the woman confides in Smalls that she's using Nick to escape the city.
As she continues, she becomes exhausted and dehydrated but resolves not to give up and
presses forward.
Unfortunately, later in her journey, a sandstorm sweeps in.
She attempts to flee from it, but the swirling sand knocks her and Smalls to the ground.
Shortly after the storm subsides, Molly regains consciousness and notices a passing vehicle.
She calls for help, leading two men, Ted and Jason, to exit the car.
Ted then offers her a bottle of water, which she eagerly drinks to quench her thirst.
She informs the strangers that she has been walking to an airfield.
Upon hearing this, the men assist her in getting up and invite her to join them inside their
vehicle.
Upon mentioning that she lost a bag in the sandstorm, Ted and Jason urge her to take
a break in the car while they search for it.
As the strangers search for her item, Molly charges her phone, activates the air conditioner,
and relishes the cold air, experiencing it for the first time in a while.
However, as Molly glances at her reflection in the mirror, she notices a photograph of
a father and son wearing Jason's cap.
When she examines the backseat, she stumbles upon prisoner clothing, leading her to suspect
that the men are not the original owners of the car.
Shortly after, Jason and Ted return with the woman’s bag and inquire about the airfield's
location.
In response, Molly, feeling uncomfortable, attempts to dissuade them from going there,
suggesting that the plane may have already departed.
Despite her concerns, Ted remains determined to head to the airfield, hoping to find another
plane for their escape.
Sensing potential danger, Molly expresses her gratitude for their assistance but insists
on leaving to continue her journey alone.
However, Ted urges her to join them due to the extreme heat outside.
When Molly tries to leave, she finds that the car door is locked.
As she demands that Ted unlock it, Jason suddenly covers her head with plastic.
Ted then leaves the vehicle and forcibly drags Molly into the sand, warning her that she
must disclose the airfield's location or else she will meet the same fate as the car's previous
owners.
Terrified for her life, Molly discloses that the airfield is six miles north of their current
location.
However, instead of releasing her, Ted engages in inappropriate behavior, taking the woman
to the back of the car and forcing himself on her.
Upon hearing the woman’s cries, Smalls emerges from the sand and attacks the evil man from
behind, rescuing Molly.
Witnessing this, Jason is horrified and rushes to the driver's seat, speeding away and inadvertently
leaving a box of supplies behind.
While the zombie consumes Ted, Molly inspects the items.
Among the bottles of water and food, she discovers an inflatable raft.
She takes it with her and suddenly breaks down in tears, overwhelmed by the devastating
events she has endured.
Upon noticing Smalls approaching again, Molly encourages herself to keep moving forward.
As she walks, the woman vents her frustrations to the zombie, acknowledging that unfortunate
events can occur even to good people, and they must move on.
Shortly after that, they encounter a spot filled with discarded tires.
Molly selects one and places it around the zombie's neck, then attaches the inflatable
raft's string to it, allowing the undead man to transport her supplies.
During their journey, Molly shares a bit about her family.
She explains that her older sister, Ali, had always aspired to be a mother but could not
have children.
Because she’s gone all the time, Ali and her husband, Blake, volunteered to care for
her son, Chase.
The woman reflects on how her sister is a far better mother to her child than she could
ever be.
She considers herself unfit for motherhood, believing that she can’t provide for her
son’s needs.
Later, Molly takes a break and attaches the raft's string to the rock, keeping the zombie
in place.
Checking her phone, the survivor realizes she’s just 2.5 miles from the airfield.
Determined to reach her destination, the woman informs the undead man that she'll leave him
behind as he's impeding her progress.
However, as Molly walks away, she suddenly changes her mind and returns to remove the
tire from Smalls's neck.
As he is about to attack her, Molly screams at the undead man, commanding him to stay.
Hearing this, Smalls complies, just like an obedient puppy.
Exerting control over the zombie, the woman continues to include him in her journey.
That night, she retrieves a tin can from her backpack and becomes emotional while holding
it.
Molly then confides in Smalls that she used to play a game called "Telephone" with her
son, Chase.
They created make-believe phones using two cans and a string.
She then places the can to her ear as if expecting to hear her son from the other end of the
line.
The next day, Molly and Smalls walk over a mile and reach the road, where they spot approaching
vehicles.
In a sudden panic, she pulls the zombie into a hiding spot, hoping to remain unnoticed.
Believing the road is safe, the survivor unexpectedly overhears people talking, indicating that
one vehicle has stayed behind to investigate the area.
To keep Smalls safe, she places a heavy rock on top of the string and hurries to the center
of the road to approach the soldiers.
Seeing the woman, they swiftly raise their guns, wary of a potential infection.
Without delay, she clarifies that her car got stuck, and she's journeying on foot to
reach the airfield down the road.
When the soldiers attempt to offer her a ride, Molly declines, stating that her husband will
join her eventually.
However, Small breaks free and suddenly approaches her, drawing the soldiers' attention, who
assume he's her infected husband.
Molly urgently implores the soldiers not to shoot the zombie.
Unfortunately, one of the officers fires a shot, hitting the undead man in the leg and
causing him to fall to the ground.
Worried, Molly rushes to Small and attempts to calm him down.
However, the wounded zombie unexpectedly bites her finger, shocking her.
Thinking on her feet, the woman immediately disinfects the wound by pouring liquor, only
to realize that the virus is gradually spreading.
Left with no alternative, she grabs a rock to amputate her finger in a desperate attempt
to stop the infection.
As she does so, she reminisces about being a first-time mother and cradling her son in
her arms.
After these events, Molly returns to Smalls, who cannot stand anymore.
To bring him with her, the woman lifts him and places him in the inflatable raft, which
she pulls as she continues towards the remote airfield.
As she continues her journey, the survivor is filled with excitement when she spots the
airfield, realizing that she's almost reached her destination.
However, her joy quickly transforms into concern when she glances back at Smalls, who tumbles
out of the raft.
Despite her attempts to motivate him to continue, the zombie cannot move.
Upon discovering the undead man’s wallet, Molly learns that Smalls was married before
becoming a zombie.
Realizing that her zombie friend is too weak to continue the journey with her, she picks
up a large rock.
Before ending his suffering, the woman expresses her gratitude for his companionship.
When she arrives at the airfield, someone fires at her from the tower.
To protect herself, she hides behind a car and demands the shooter to stop.
Jimmy then recognizes her voice and heads down to meet and bring her to the hangar.
There, Jimmy reveals that one of his men was bitten by a zombie, subsequently infecting
the other four men.
As a precaution, he has locked them all in a room.
Shortly afterward, the pilot, Robbie, prepares the plane and invites them to board for their
journey to Mexico.
However, Molly stays behind, hopeful of reuniting with her child.
Determined to reach her son, Molly heads to the airfield's control tower and uses a phone
to call her sister three times but receives no response.
On her fourth attempt, Chase answers the phone, disclosing that he is still inside the house.
When Molly inquires about her sister Ali, her son reveals that he was told to lock the
door and has been hiding in his bedroom for a long time.
Upon hearing this, the woman instructs Chase not to leave his location, regardless of what
occurs, as she reassures him that she'll be coming to get him.
Afterward, Molly runs toward the convertible in the airfield to drive it.
However, she cannot locate the keys and deduces that the owner must be inside the locked room.
She manages to break into the room using a tool but encounters two zombies inside, neither
of whom has the car keys.
When Molly spots the third zombie, she panics and tumbles to the ground, accidentally dropping
her tool.
The undead man starts to attack her, leading her to reach for a nearby drill to defend
herself.
After a desperate struggle, she manages to defeat the zombie.
Following this, she searches the creature's pockets and, at last, gets a hold of the car
keys.
To rescue Chase, she drives the convertible and heads back to Las Vegas.
During the journey, she reminisces about her time with her son when he was just a baby.
Upon her arrival in the infected city, she observes abandoned cars and lifeless bodies
strewn across the streets.
She then acquires a shovel from a pickup truck and enters her sister's house, where she finds
her deceased brother-in-law, Blake, in the kitchen.
As she walks further, Molly finds a note on the glass door written by Ali, revealing that
her sister had to set herself on fire because she had been bitten.
Subsequently, Molly proceeds upstairs searching for Chase but fails to locate him.
It's in her son's bedroom that she becomes emotional upon encountering his child's tin
can, thinking he’s gone.
Upon hearing a strange sound, she quickly grabs her shovel and heads to the play area,
where she discovers Chase inside a kid tent.
Tearfully, Molly hugs her son, apologizing for leaving him and making a heartfelt promise
to always be there for him.
Following their heartwarming reunion, she invites her son to leave the house with her.
As she helps her son put on his shoes, a horde of zombies breaks into the house, prompting
her to grab her weapon.
Preparing for combat, Molly instructs Chase to stay back, no matter the circumstances.
As the undead approach her, the courageous woman strikes one of them with her shovel.
