Nena Herrera-Casey is the coyota, the youngest, in her large Mexican-American family. Her life in Albuquerque seems placid enough, teaching Spanish part-time at the University and selling handicrafts imported from south-of-the-border at the flea market. But Nena has nightmares, vivid, chilling, violent and recurring. When she overhears two Drug Enforcement Agents' whispered conversation, she becomes unwittingly entangled in a mysterious 'accident', a fiery plane crash that kills a former student. Was the conversation she overheard actually the plot to murder him? As her life unravels, rogue DEA agents conspire to set her up on bogus drug charges. And her worst nightmare stalks her through the Mexican desert.
