A dead mother. A missing father. A mysterious man. They all spell trouble for private investigator Carol Sabala. When Carol's mother dies unexpectedly, Carol is left with no family-only money, grief, and an envelope. Her mother has charged her with a mission: deliver the envelope to her long-lost father. Enroute to Zihuatanejo, Mexico, to track down her father, Carol encounters the alluring Mark Escalante, who snares her in a deadly pursuit of his own.
