Between the gray twilight of the Great Depression and the perilous dawn of World War II, from 1936 to 1942, a heartwarming story of extraordinary loyalty quietly unfolded along the Great Northern Railroad in the remote little prairie town of historic Fort Benton, the birthplace of Montana.  A story of faithfulness so unbelievable it warmed the world's heart as it was recorded in the pages of Ripley's Believe It Or Not. 

This is the story of Shep, the once vagrant mongrel who became America's most legendary dog.  Strong principles and simple virtues, taught by a long-departed master, were exemplified by the life of his loyal dog while keeping a five-year lonely vigil for the master's return.

Shep's amazing story now belongs to the ages, a classic piece of American history told and retold throughout the years by the Associated Press, UPI, Reader's Digest, Paul Harvey, and other major publications.  A story of a noble dog, a soul "forever faithful", and an undying love for his master that endured the hardships of mortal existence and never wavered.  A story told through the eyes of a young family struggling against personal misfortune, and the adversity of hard times in an unfamiliar town, a town of a last frontier.
