In 1936, a sheepherder in Montana died and the family sent his body east for burial. As the casket was loaded into a baggage car at the train depot, the sheepherder’s dog appeared out of nowhere and began to whine. Shep, as the dog came to be known, faithfully met every incoming train for the next six years in search of his master who would never return. Shep’s true story of unwavering devotion became legendary and serves as the basis for this fictional tale of a young boy’s struggle with feelings of loss and betrayal. As Shep’s and Ben’s stories meld, Shep’s simple and undying faith becomes Ben’s faith.
