Third generation Texas Ranger Tyler Steele is the last of a dying breed --- a modern-day cowboy hero living in a world that doesn't quite understand his powerful sense of right and wrong and instinct to defend those who can't defend themselves. Despite his strong moral compass, Ty has trouble seeing his greatest weakness. His hard outer shell, the one essential to his work, made him incapable of forging the emotional connection his wife Andie so desperately needed.

Now retired, rasing their son Brodie on his own, and at risk of losing his ranch, Ty does not know how to rebuild from the rubble of his life. The answer comes in the form of Samantha and her daughter Hope, on the run from a seemingly inescapable situation. They are in danger, desperate and alone. Though they are strangers, Ty knows he can help --- protecting the innocent is what he does best. As his relationship with Sam and Hope unfolds, Ty realizes he must confront his true weaknesses if he wants to become the man he needs to be.
