The conquest of Mexico is over, and Juan de Toñanes is just one of the many inglorious soldiers eking a small existence on the land he helped conquer. When he receives one last mission, to hunt down a renegade Indian who calls himself the Padre and preaches a dangerous heresy, Juan realizes it may be his last chance to create the future he's always dreamed of. But as he moves deep into the unexplored northern territory, hot on the Padre's trail, Juan discovers the traces of a man who appears to be, in fact, a prophet destined to transform his own time, and possibly future to come. On his quest, Juan will encounter old conquistadors on horseback and migrants riding the roofs of the trains, rebellious Indians and peasants waiting patiently for a better world, Mexican revolutionaries brandishing their rifles and women murdered in the desert of Ciudad Juárez, all sharing the same landscape and the same hope: that the arrival of the Padre will bring ever elusive justice to the oppressed.
