Three in Exile (1925)

After severely injuring his foreman in a fight, railroad worker Art Flanders flees to the desert, where he finds companionship with a dog named Rex, and later, with Black Beauty, a runaway horse. In their search for water, the three come upon a stream on the property of Lorraine Estes, owner of a mine claim that Jed Hawkins plans to usurp. While Art does the manual labor necessary to register the claim, Jed sends several of his men to dynamite the mine. They are thwarted by Art and Black Beauty, who also bring Jed to justice. One year later, Art and Lorraine are married with a baby, and Rex is father to a litter of puppies. Black Beauty is relegated to flirting with a hobby horse.
