After their father's death plunges the family into crisis, their mother sends them north to find work and send money home before the family loses its house. The siblings face dangers at every step — beatings, bandits, border crossings, and immigration raids — as they make their way from Ensenada through Tijuana to Colton and finally to Indio. Once settled with Aunt Consuelo, Salvador falls under the influence of the flashy pocho Lucio and gradually abandons his responsibilities to Lupita and the family in Mexico. The story reaches its turning point when la migra raids a Valentine's Day dance and arrests Salvador, leaving Lupita entirely on her own. Rather than surrender, Lupita resolves to learn English and build a new life in Indio, finding unexpected encouragement from her young cousin Irela.

The siblings learn hard lessons about trust — that Señor Rosario's advice can mean the difference between arrest and escape, that a pocha waitress can save them when la migra strikes, but that safety is always precarious. Life in Indio brings its own hardships, from crushing fieldwork and cultural humiliations to the slow erosion of Salvador's commitment to his family.

The story begins with a family in shock, gathering to make impossible choices — including sending two teenagers into the unknown with little more than a borrowed address and a hidden money pouch. Every new discovery along the way — a coyote who flees at the first sign of trouble, a desperate classmate who can open a door, a railroad worker who chooses kindness over self-interest — forces the siblings to adapt quickly and trust their own judgment. The arrival at Consuelo's crumbling house shatters the dream of a wealthy aunt and confronts the siblings with a harder reality than they imagined. Salvador's drift toward Lucio's world and his cold treatment of Lupita at the Valentine's Day dance finally break the bond between them, freeing Lupita to act for herself. The pool closes with Lupita's determined request to learn English — her clearest declaration yet that she will build her own future on her own terms.
