In April 1528, 400 conquistadors, dreaming of gold, land in Florida to begin the exploration and conquest of what is now the southern United States. After terrible months of trekking northward, fighting off hostile Indians in the swamps of Florida, they build boats and try to escape to Mexico. Most are never seen again. This is the tale of four survivors shipwrecked on the shores of Texas and in particular that of Alvar Nuñez Cabeza de Vaca, who wrote it all down many years later. Living among the Indians of the coast for five years, Cabeza de Vaca finally rejoins the three others; together they embark on an epic walk across America to the Pacific coast, reappearing in Mexico eight years after they were lost. Wood travels to the Pacific along ancient Indian trails walked by the Spaniards and visits the spectacular Native-American city of Casas Grandes.
