Warner Baxter plays the ambitious producer of a burlesque show who rises to the big time on Broadway. Alice Faye is the loyal burleycue singer who helps make Baxter a success. His head turned by sudden fame, Baxter falls under the spell of a society woman (Mona Barrie) who has theatrical aspirations of her own. She marries Baxter, then convinces him to produce a string of "artistic" plays rather than his extravagant musical revues. The plays are flops, and the woman haughtily divorces Baxter. Faithful Alice Faye, who'd gone to London when her ex-beau was married, returns to the penniless Baxter. She and her burlesque buddies team up to pull Baxter out of his rut and put him on top again.
