Lucy Walsh's heart remains with the struggling town of Paragon Springs but she feels beholden to her husband, Admire, to make the Run to the Cherokee Strip for new land. Admire married her when few men would have, and raised her half-Sioux daughter, Rachel, as his own. When Admire is killed for his Strip claim, Lucy, grieving, leases the land to his cowboy friends and returns to Paragon Springs and gets by on her tidy farm. In 1910, an eccentric new neighbor, Tom Reilly, begins building a new-fangled "aeroplane" in his barn and Lucy, convinced that he's onto something that could help her town, determines to build an aeroplane plant with oil money she's come into from her Oklahoma land. Together, they'll face ridicule from friends and family, go to air shows and learn from other aviation pioneers, and deal with the shallow aviatrix Sophie, to find a way to lay out plans for ParagonSprings' future.
