But when Judd starts threatening to take "his" dog back, Marty is afraid of losing the best friend he's ever had. Even after Shiloh's keen senses help save Judd's life, the old man refuses to mend his mean-spirited ways, convincing everyone in town he's just too nasty to change. Now, in a long-short gamble to keep the dog he loves, Marty sets out to prove that just like a mistreated animal, a man filled with hate can be healed by the power of kindness.
