Photographer Nellie Burns and her Labrador retriever, Moonshine, travel with
sheep rancher Gwynn Campbell and his Basque sheepherder, Alphonso, to the
Stanley Basin of central Idaho. Nellie plans to spend several weeks in the
mountains around the basin at a sheep camp, photographing scenes for a railroad
company’s travel brochures. When their group arrives at the camp, they discover
the current herder is dead. Basque sheriff Asteguigoiri arrives to seek the
murderer and reluctantly accepts Nellie’s help in the investigation. But when
hapless tourists, lawless moonshiners, and hell-bent cowboys enter the picture,
Nellie and Moonshine confront the greatest challenges yet to their courage and
ingenuity.
