Following the death of his young wife, Devon has exiled himself to the lonely outrider's cabin of his family's ranch.

There, his solitude is shattered by the unexpected discovery of a young woman, thrown from a train in an obvious attempt at murder. Her memory gone.

Instinctively, he shelters and protects her. Hides her away from the world. As the two of them observe and help each other in the day-to-day workings of a modern ranch, their regard grows.

But they know that their new-found happiness is threatened. Somewhere, there is someone who wants to separate them. Someone who wants her dead. It will take all of their courage and ingenuity to unravel the mystery. And stay alive.
