When 13-year-old Olive Oatman's wagon train is raided by outlaw Yavapai Indians, she and her sister are captured. After enduring harsh treatment, they are ransomed by a band of Mohaves. Olive struggles to adjust to her new life, but finds comfort in her faith and in an unexpected friendship.
When the time comes for her to return to the previous world she once knew, she is afraid she will never fit in. But she learns to see the Mohave design tattooed on her chin as a sign of God's love and deliverance, a mark of ransom.
