Disaster strikes a wagon train en route to Texas, leaving 18-year-old Abby in charge of the survivors, all children younger than her. After an attempted kidnapping, the others convince her to disguise herself as a boy. Initially reluctant, Abby soon realizes life on the trail is much easier without bulky skirts. The disguise allows her to do things as "Abner" she couldn't do as Abby. It's intoxicating.
Disfigured by fire as a child, Manny, a young cowboy, is lonely and yearns for companionship. His scars and the judgment of townspeople make it difficult for him to trust others. He intercepts the wagon train and agrees to help the children finish the trip to San Antonio. A new friendship cracks the protective walls built around his heart. Hope blooms when he meets "Abner," and Manny's fear of rejection slowly dissolves.
As the weeks on the trail go by, Abby develops romantic feelings for Manny, and he values his first new friendship in years. When Manny discovers her deception, it destroys the fragile bond of friendship growing between them.
Can God help the two young lovers find trust, faith, and forgiveness on the hot Texas plain?
