Driven to understand the hard realities of the landscape he loves, Cantú joins the Border Patrol. He and his partners learn to track other humans under blistering sun and through frigid nights. They haul in the dead and deliver to detention those they find alive. Plagued by a growing awareness of his complicity in a dehumanizing enterprise, he abandons the Patrol for civilian life. But when an immigrant friend travels to Mexico to visit his dying mother and does not return, Cantú discovers that the border has migrated with him, and now he must know the full extent of the violence it wreaks, on both sides of the line.
