Big Town Girl is 20th-Century Fox's spin on Paramount's
Carole Lombard vehicle The Princess Comes Across. Whereas Lombard played a Brooklyn girl posing as a Swedish princess, Big Town Girl's
Claire Trevor plays a department store song plugger who becomes a radio singing sensation by posing as the mysterious "Masked Countess." This publicity ploy serves a double purpose: Trevor is the estranged wife of gangster
Alan Baxter, and she doesn't want Baxter to know her whereabouts. Reporter
Donald Woods tumbles to Trevor's deception, but he falls in love with her and determines to keep her secret. ~ Hal Erickson, All Movie Guide
