Miguel receives a letter from Papá on his fifteenth birthday saying it is finally time to join him across la línea.

Miguel visits Don Clemente, who gives him cash and instructions but reveals Papá refused help bringing the whole family north.

Abuelita gives Miguel her beloved Virgen de Guadalupe medallion and blesses him at their tearful final goodbye.

Miguel boards a northbound bus and meets Javier, a talkative older migrant from El Salvador traveling to New York.

Capitán Morales stops the bus, collects bribes from passengers, then lifts a disguised migrant's shawl to reveal Elena.

Morales loads Miguel, Elena, Javi, and the other single male migrants onto a transport van bound for the Guatemalan border.

Javi fakes a convincing seizure at the border crossing, creating a diversion that lets the migrants scatter and escape.

An armed thief named Colmillo robs Miguel and Elena at gunpoint on a market portico and threatens Elena.

Miguel calls Don Clemente for help but learns he was killed in a car accident and Juanito now runs his operation.

Miguel, Elena, and Javi successfully board the mata gente freight train, watching in horror as others are killed or injured in the attempt.

Soldiers stop and board the freight train, forcing the three to jump off into the brush, and Javi badly injures his ankle.

A professional smuggler named Moisés equips the group with desert gear and personally leads them out into the open desert at sunset.

Armed militia members in a jeep shoot Moisés and capture him, but he manages to push his backpack out for the group.

After sheltering from a sandstorm, Miguel and Elena wake to find Javi gone, leaving only his partially full water bottle behind.

Ten years later, Miguel phones Elena from California; she has returned to Mexico and taken over Abuelita's rancho.

Miguel receives his father's long-awaited letter calling him north on his fifteenth birthday, setting off a journey full of danger and hardship. After a tearful farewell with his grandmother, Miguel boards a bus north where he unexpectedly discovers his younger sister Elena has secretly followed him in disguise. Caught by corrupt federal police and nearly deported to Guatemala, the siblings escape with the help of a fellow migrant named Javi and press on despite being robbed of nearly everything. Traveling by freight train and truck, they reach the US-Mexico border, where a professional smuggler named Moisés equips them and leads them into the scorching desert. Armed militia members shoot and capture Moisés, leaving the trio stranded with dwindling water and no guide. Through desperate perseverance, Miguel and Elena survive, and a decade later the two siblings reconnect by phone, each having built a life on opposite sides of la línea.

The headline events of Miguel and Elena's dangerous journey to cross la línea.

Elena shows Miguel a letter from Mamá containing a photo of the three-year-old twin sisters they have never met.

At Miguel's farewell party, neighbors and relatives trade cautionary stories about kidnappings, organ theft, and migrants who disappeared crossing the border.

Friends Lalo and Chuy give Miguel their only valuables as farewell gifts, and the three make a ten-year reunion pact.

Miguel slips away before dawn without waking Elena to say goodbye, knowing the deliberate snub will hurt her.

The transport van swerves on the road to Guatemala, Morales falls, and his pants slip down exposing him to the laughing migrants.

Furious at Elena for ruining his plan, Miguel seizes her money and buys two bus tickets back to San Jacinto.

After the robbery, Elena reveals she secretly sewed half her money inside the lining of her purse before leaving home.

Javi leads Miguel and Elena to a hidden spot in the brush near the freight train tracks where migrants wait safely from patrols.

Javi advises Elena to cut her hair short to pass as a boy, and has Miguel write 'Tengo SIDA' on her chest.

As the freight train slows through a village, townspeople run alongside it tossing food, water, and clothing up to the riders.

A criminal gang boards the freight train and drags several screaming girls into the bushes while a terrified Elena watches.

Without consulting Miguel, Elena secretly pays an old Native couple to arrange a truck ride north for the entire group.

At the border town market, the group reads news headlines about a massive freight train derailment that killed hundreds of child migrants.

El Plomero tests Miguel's loyalty by falsely claiming he spoke with Don Clemente that very morning.

Near collapse from dehydration, Miguel and Elena crest a final desert hill and spot the busy highway Moisés had promised.

Before Miguel departs, Elena shows him a letter from their mother revealing the twin sisters they have never met, deepening her desperation to go north. At his farewell party, friends and family share dark cautionary stories, and Miguel's childhood friends give him their most precious possessions before he slips away without saying goodbye to Elena. Along the journey, small moments carry heavy weight: Capitán Morales's humiliating mishap on the transport van, the discovery of Elena's secretly hidden reserve money after their robbery, and Javi's careful preparations to protect Elena before they board the deadly freight train. The kindness of townspeople who toss food and water to the train migrants contrasts sharply with a gang attack on female riders and the chilling news of a deadly derailment. At the border, a smuggler quietly tests Miguel's honesty before agreeing to guide them, and eventually the two siblings drag themselves to a final desert hilltop to see the highway that means survival.

The smaller but vital moments that shaped each step of the siblings' trek north.

Abuelita sharply tells Miguel he is too hard on people and too quick to judge others, especially his own father.

Elena tearfully confronts Miguel, insisting it is unfair that he gets to cross la línea while she must stay behind.

Elena kills the farewell goat with a single calm hammer blow while Miguel watches, too queasy to hide his discomfort.

Looking in a mirror before leaving at dawn, Miguel is surprised his face looks exactly the same despite feeling completely changed inside.

Miguel instinctively calls out Elena's name when Morales lifts her shawl, directly causing both siblings to be arrested.

Elena confesses she got her travel money from Juanito and learned the route by secretly reading the instructions Miguel had hidden from her.

After Elena reveals her hidden reserve money, Miguel decides they will continue north together rather than sending her back to San Jacinto.

Miguel spitefully tells Elena that Papá refused Don Clemente's help for years, revealing the family could have been reunited much earlier.

Miguel walks alone to camp by the train tracks, then spots Elena watching from the cornfield and chooses to rejoin her.

An older man reaches for Javi's outstretched hand while trying to board the moving freight train and slips beneath the wheels.

During the first night of desert walking, Moisés teaches the group how to conserve moisture, avoid snakes, and ration their water.

The group stumbles upon the bodies of a migrant woman and child lying together on the open desert floor.

Javi, growing confused and slurring his words, tells Elena that Miguel is their leader now and she must follow his instructions.

Huddled against Miguel during the sandstorm, Elena forgives Papá and asks Miguel to promise that California will be worth everything they suffered.

Miguel eventually graduates college and forgives Papá; Elena returns to Mexico, marries Chuy, and names her baby Miguel Javier Moisés.

Miguel's journey is as much internal as external, beginning with his grandmother's warning that he is too quick to judge others and Elena's raw hurt at being left behind. A series of revelations force Miguel to confront his assumptions: learning Elena had her own plan and her own funds, and discovering how Papá's stubborn pride had kept the family apart for years longer than necessary. Miguel's willingness to abandon Elena and Javi whenever they inconvenience him reveals his immaturity, but each crisis chips away at his self-centeredness until he chooses family over pride and camps near the train tracks alone before turning back for his sister. On the mata gente, witnessing a man die beneath the train wheels strips away Miguel's remaining naivety about the true stakes of their journey. In the desert, the discovery of a dead mother and child and Javi's quiet self-sacrifice complete Miguel's transformation into a leader who refuses to leave anyone behind, a change confirmed a decade later when he finally forgives his father.

The key decisions, discoveries, and emotional shifts that define Miguel's coming-of-age.
