On one of the first runs through Texas, Butterfield Overland Mail Company driver Ned Bright carries two Ursuline nuns returning to their mission station. They come across a woman who is nearly dead from exposure and dehydration and take her to the mission.
With some detective work, Ned discovers Taabe Waipu's identity. He plans to unite her with her family, but the Comanche have other ideas, and the two end up defending the mission station. Through Taabe and Ned we learn the true meaning of healing and restoration amid seemingly powerless situations.
