The temptress lured a hack composer and song plugger (John Beal banging the piano keys in a boarding house all hours of the night) away from his true love, Hillary Brooke. Once his night club act runs its course, she dumps him and takes up a job as "the other woman" in an alimony racket headed by shyster lawyer (Douglass Dumbrille).
So corny and cliched that it is good for laughs.
