In the years before the United States' involvement in World WarI, John Merrick and Jerry Somers, attachés to the American embassy in Vienna, attend an elaborate fundraiser at the aristocratic Walden home where John meets the lovely Countess Vilma Walden and romance blooms. Vilma's twin brother, Count Carl Walden, a combat veteran, along with Vilma and Carl's father asks John when Americans will fight against Austria. Kapitan Wolke, a family friend, emerges as a rival for the affections of Vilma. A heated confrontation takes place between John and Wolke. When the United States goes to war, John requests a post at the Italian front where Carl is stationed. John returns to the Walden home and breaks the news to Vilma, Vilma then promises to return to the pool by the house, each day until John's reflection appears beside her own. After duty in France, John is transferred to the Italian front where he faces an enemy squadron, led by Wolke and his "second-best" flier, Carl. In the air over the Italian Alps John spots Wolke's aircraft and shoots it down, landing nearby to try to rescue the pilot. John is astonished to discover that the pilot is actually Carl, who had borrowed Wolke's aircraft for the mission. John is overcome with grief and announces that he is through with killing. After refusing to join his squadron on a flight against the enemy, John steals an aircraft and flies to the Walden house behind enemy lines. He confesses to Vilma that he killed Carl and begs her forgiveness, but she refuses. For his desertion, John is court-martialed with Jerry, his defense attorney, unsuccessfully defending him. Despondent and apathetic, he is found guilty and receives a dishonorable discharge and a sentence of hard labor. Peace finally comes and John goes to visit the Walden estate, now turned into a home for war orphans. As Vilma sits by the pool, she sees John's reflection beside hers, and the reunited couple embrace.
In August 1931, Fox rented the three modified Nieuport 28s for Heartbreak ; a Travel Air 4000 was also leased. A Royal Aircraft Factory S.E.5 is also in German markings as Wolke's aircraft. Garland Lincoln and Frank Clarke did the flying in the aerial battles over the San Gabriel Mountains east of the Los Angeles Basin.
