Loretta Dalrymple, a homely young country girl comes to New York City and gets a job as a chambermaid in a large hotel. She meets Ed Olson, a photographer out of work, and Dan Riley, a promoter with nothing to promote. When an advertiser offers a reward for a photograph of 'America's Prettiest Girl,", Ed makes a composite photo of all the famous movie stars and society belles and calls the girl in his picture "Dawn Glory." A Dawn-Glory craze sweeps the country, and Loretta, with makeup and new clothes, turns out to be the reincarnation of the picture. Loretta has fallen in love with a newspaper picture of "Bingo" Russell, a famous aviator, and when Dan and Ed ask her to pose as Dawn Glory, she readily agrees, hoping she will get to meet Russell. She does meet him and, then, complications arise.
