In 1952, the presidential candidate of the PUM political party Carmelo Barriga visits the rural town of San Jilemón el Alto where he gives a speech promoting his candidacy and political party. During the speech and among the townspeople, a young woman gives birth to two twin girls. In a political move, Carmelo decides to adopt one of the girls whom he names Lorena and who becomes an active politician in her own political party, the PUF. Lorena then becomes a presidential candidate running against her rival, Santos Barboza of the PUM. When Lorena and her campaign visits San Toribio del Trueno, a firework accident causes her to abandon the candidacy. Fortunately, campaign member Gonzalo remembers about Lorena's twin and decides to search for her so that she can substitute Lorena and therefore the campaign can resume.
