Amalgamated Pictures is seeking new stars for its motion pictures. Talent scout Thomas Brooke hits the road, looking for newcomers to bring back for screen tests, hopefully to impress the studio's boss, Dane Wharton.[4]
Brooke discovers a football player in Arizona who can sing, Bud Borden, and a talented Texas singer, Mary Andrews. On a visit to Arkansas, his presence is discovered by aspiring actress Carolyn Sayres, who schemes to get Brooke to take an interest in her. He does, at least until he finds out she's still a bit too young.
Everyone travels to Hollywood for screen tests and a visit to Grauman's Chinese Theater, where they get a kick out of the footprints of movie stars embedded in the cement. Brooke encounters the casting director's own new find, June Lawrence, a singer. He clashes with the studio, which offers a contract only to Mary and sends his other discoveries home.
Carolyn doesn't take no for an answer and comes back. Brooke now gets in her corner and schemes to insert footage from her screen test into a theater's newsreel. The next thing they all know, not only is Carolyn a star, Grauman's is inviting her to be immortalized in cement.
