With World War I afoot, David Armstrong (Richard Arlen) and Jack Powell (Charles "Buddy" Rogers) join the military with an eye toward flying American fighter planes. They leave behind Mary Preston (Clara Bow), a local girl who's in love with David but committed to Jack. Dispatched to France as newly minted pilots, the men take to the skies in one of the war's climactic air battles, and as frantic Mary longs for the safe return of both men, one pays the ultimate price for his bravery.
