After trouble with his family and much debate, dejected rancher Jeremiah Jackson sets out from San Antonio to make his fortune mining gold in California. With his heart full of hope and determination burning within, he forges through the Sierra Nevada Mountains searching to stake his claim. But instead of finding a successful life independent of his family, he is robbed, beaten and left for dead.

Drifter Calliope Winters and her con man friend Eli are on the run from the law. They are trying to run as far as they can but when she sees Jeremiah on the side of the road she insists they stop and rescue him. As she nurses him back to health, they both are drawn toward each other.

Both have their secrets, which they are reluctant to share, but as the bond between them grows, they realize they have to learn to trust before they can ride off into their San Antonio Sunset.
