It's 1927-the late days of the barnstorming era, when pilots competed with each other by performing deadlier and more wondrous feats. Injured pilot Hawk E. Baron served on the frontlines of the war. Still a young man, he's an adventurer who lives his life traveling from town to town in his plane entertaining folks-most of whom have never seen a car, let alone a plane. His world changes when he meets Tillie, a young woman who shares his passion for aviation and adventure. They become a traveling act, delighting folks with their antics. Tillie even becomes Hawk's wing-walker, climbing out on the wing of the plane mid-flight to perform death-defying acrobatics. When they learn they are suspected of a horrific crime, their journey becomes an even deadlier race against time. Along the way they bond, confessing their secrets, and begin a romance in this lush, character-driven series that explores the early days of aviation and the evolving relationship and romance between two young pilots.
