Ronnie Bowers [Dick Powell] is a saxophone player and singer heading to Hollywood after being signed to a ten-week contract by All Star Pictures. At the airport, his former employer, Benny Goodman [Benny Goodman], and his band give him a big sendoff, performing Hooray for Hollywood. The trip marks the start of a collision between showbiz energy and romantic misadventure that will test Ronnie’s ambitions and his heart.
In Hollywood, temperamental star Mona Marshall [Lola Lane] becomes furious when she learns that another actress has landed a role she desperately wants, and she refuses to attend the premiere of her latest film. Publicist Bernie Walton convinces studio boss B. L. Faulkin [Grant Mitchell] to substitute a double for the glamorous lead. Bernie selects Virginia Stanton, who has already stood in for Mona, and for her escort he chooses the unsuspecting Ronnie. The ruse works, fooling not only the press but everyone at the premiere, including Louella Parsons and the radio host. The film world buzzes with the surprise, and Ronnie and Virginia begin to fall in love, wading in a fountain pond and singing I’m Like a Fish Out of Water. The moment crackles with a charm that hints at a bittersweet twist ahead, as real feelings threaten to overturn the plan.
The next day, Bernie takes Ronnie to lunch at the restaurant where Virginia works as a waitress. He breaks the news of the ruse and Ronnie and Virginia start dating in earnest, even as questions linger about the double who sparked their romance. The plot thickens when Mona learns from the press that she was seen at the premiere with Ronnie, forcing Faulkin to buy Ronnie out of his contract. Fuzzy Boyle [Ted Healy], who appoints himself Ronnie’s agent, helps hustle the young man into public appearances, but their chances of making it in the film industry are limited until a new opportunity arises.
Ronnie’s path changes when director Walter Kelton [William B. Davidson] is impressed by Ronnie’s singing during a drive-in gig and offers him a job. The catch is stark: Ronnie will not act, but will provide the dubbing for Mona’s longtime screen partner, Alexander Dupre. Dupre’s “singing” proves popular at the preview, and Louella Parsons invites him to broadcast on her radio program. All Star Pictures agrees to pay a handsome fee to have Ronnie sing for Dupre, but Ronnie has his own ideas about where his career should go. Virginia (posing as Mona) even arranges a ride to pick up Dupre in a limousine driven by Fuzzy Boyle, hoping to derail the program. In a bold move, Ronnie steps in for Dupre and becomes a hit, prompting Faulkin to re-sign him at a larger salary, establishing him as a rising star in a crowded, ever-watchful industry.
The film’s world is filled with a chorus of industry figures and a sense that fame can be manufactured just as quickly as a tune can be sung. In the background, The Russian [Fritz Feld] and other colorful supporting players punctuate the backstage energy of Hollywood’s spectacle, while the interplay of deception, ambition, and romance unfolds with warmth and a steady, light touch. The movie is a bright, jazz-inflected look at show business, where a chance romance can bloom amid the glare of premieres, publicity stunts, and the constant push to reinvent a career in the public eye.
