Note: The novel can be updated to reflect current events.

A Mexican/American narrates (first person singular): he remarks on the differences between Americans and Latinos and states the events that have sparked an international conflict between Mexico and the U.S., on account of the March North, which began on May 14. It is made up of Mexican women (joined over time by other Latino women), in order to hold, a protest rally against the U.S. at the Reynosa sports stadium. They complain about emigration to the north (providing cheap labor), the resentment of many abandoned mothers, wives and families, the economic crises and the high and disorderly US import tariffs for Mexican agricultural products and others. Demorada is the leader of the march: a 90-year-old woman, native and resident of Santo Tomás, North of Veracruz, cultured, 1.50 m tall, white-haired and devoted to The Virgin of the Mangos (The Virgin).

The story of Demorada is told (third-person omniscient): her marriage, her husband’s infidelities, the creation of a group of women she leads, dedicated to vaccinating and teaching the region to read, the appearance of The Virgin, the story behind it (based on the chronicle of the Virgin of Guadalupe), the way Demorada becomes the apostle and principal promoter of the Virgin, the various miracles of the image and the growth of the faithful. Secondarily, the surprising cultivation of mangoes. Demorada suffers an embolism and is prescribed medicine, with a risk of death if she fails to take it. The United Mango Company, with a cambray mango project, defrauds the mango farmers of the region. Between Demorada and her lawyer granddaughter Ofertoria, who acts as the legal adviser for the Veracruz farmers, the idea arises to form GlobaIntegraL, to fight for globalization not only economically but politically, monetarily, and socially. In Santo Tomás, the date of the 61st anniversary of the appearance of The Virgin, Demorada appears before a microphone, under the initials of GlobaIntegraL. She is applauded by women wearing t-shirts, posters, insignias and flags of The Virgin. Demorada urges them to carry out the March North toward Reynosa. Here, the two-level narrative ends to continue in third-person omniscient and chronologically.

On Saturday, days later, at the Reynosa sports stadium, they hold their meeting and decide to demonstrate on the international bridge that crosses to Hidalgo City. Severe conflict arises when they meet armed Border Patrol agents. Several dramatic events happen, reported by international media. Social media grows dramatically. Demorada takes her medicine, walks alone the bridge, crosses the line and is knocked down by an agent and arrested. Ofertoria begins to walk and suffers the same treatment. Another and another follow. One by one. The agents no longer beat them. They arrest them. The President of the U.S. asks for the intervention of the Mexican government and threatens sanctions. The women's cry arises: "Let´s go to Washington." On Monday morning the President of Mexico states that he cannot legally prohibit Mexicans to leave the country. On the US side, pro and anti-Latinos arrive. At noon, a bomb explodes in the women’s line. Demorada is back and announces she will stay there until she dies. Again, she heads toward the agents, is arrested and taken to a stadium where nearly 2,000 prisoners of the group are held. International pressure arises requesting permission for the women to pass. Countries worldwide send food, clothing, tents and medical aid for the women. Night falls, during which three of the women wounded by the bomb die.

On Wednesday morning the U.S. opens the border. The prisoners in the stadium are brought to join the others. All are issued temporary visas. They all rest in anticipation of the following morning, when they will begin the March North to Washington.
