Two young men, one rich, one middle class, both in love with the same woman, become US Air Corps fighter pilots and, eventually, heroic flying aces during World War I. Devoted best friends, their mutual love of the girl eventually threatens their bond. Meanwhile, a hometown girl who’s the lovestruck lifelong next door neighbor of one of them, pines away.

The most important family in Hickoryville is (not surprisingly) the Hickorys, with sheriff Jim and his tough manly sons Leo and Olin. The timid youngest son, Harold, doesn’t have the muscles to match up to them, so he has to use his wits to win the respect of his strong father and also the love of beautiful Mary.
