Former Marine Jake Porter has far deeper scars than the one that marks his face. He struggles with symptoms of PTSD, lives a solitary life, and avoids relationships.

When Lyndie James, Jake's childhood best friend, lands back in Holley, Texas, Jake cautiously hires her to exercise his Thoroughbreds. Lyndie is tender-hearted, fiercely determined, and afraid of nothing, just like she was as a child. Jake pairs her with Silver Leaf, a horse full of promise but lacking in results, hoping she can solve the mystery of the stallion's reluctance to run.
