Plot.
Aspiring songwriter Karl Roder (Douglass Montgomery) travels to the big city, along with a girl he is in love with, Sieglinde Lessing (June Lang), and her Father Walter Lessing (Al Shean) who has just written a new song that he thinks will take the world by storm (with lyrics by Karl). 
They stumble into the stormy relationship of Opera star Frieda Hotzfelt (Gloria Swanson), and librettist Bruno Mahler (John Boles) who constantly bicker and make up. When the composer for their new show suddenly leaves town, they decide to use Walters song, partially out of convienince, and party due to the fact that Bruno has fallen in love with Sieglinde, and Frieda has fallen in love with Karl, though he does not reciprocate.
Karl, realizing the city is no place for him, decides to go back to the village, but Bruno convinces Sieglinde that she is destined for the stage, and she stays behind to replace Frieda as the Prima Donna in the opera. However, as the opening night approaches, the cast and crew all determine that Sieglinde can not act, and they ask Frieda to come back and star in the show.
Walter calls them all cruel for breaking his daughters heart, but they tell him that the audience is crueler, and they are being spared the worst of it. At the end of the day, the feelings of two amateurs are not more important than the livelihood of the crew who deserve to put on a good show.
Sieglinde and Walter return to their town, and Sieglinde goes to apologize to Karl with her tail between her legs for not listening to him, but Walter can still be proud that his music is featured in a real show, and the whole town listens to it together on the radio. Meanwhile, Frieda and Bruno are together again, and also fighting. .
