Hetta Coffey is a woman with a yacht, and she's not afraid to use it! As a self-employed engineering consultant with a penchant of oddball (read: shady) projects, she has a way of attracting trouble. With her floating home dry docked for repairs in Mexico, Hetta needs a place to live and a job to pay for boat repairs. Landing a project at a mining operation not far from her boat, Hetta finds herself on the tumultuous Arizona/Mexico border, where all hell is breaking loose even before she gets there.
