Kansas City manicurist Rosie Sturges (Joan Blondell) is in a relationship with minor gangster Dynamite Carson (Robert Armstrong), much to the annoyance of her friend and roommate Marie Callahan (Glenda Farrell), a fellow manicurist looking for a rich husband. Dynamite and Rosie crash a date of Marie's with a wealthy customer; Dynamite gives Rosie an engagement ring, while his antics scare off Marie's date. Marie urges Rosie to drop Dynamite, and go after the three things a girl really needs "money, jack (fur), and dough (diamonds)." When Dynamite goes out of town, Marie urges Rosie to go on a date with a customer, Jimmy the Duke (Gordon Westcott), who steals the ring. Unbeknownst to the girls, Jimmy is an associate of Dynamite, who is furious to find that Marie went on a date behind his back.

Fearing Dynamite's anger, Rosie and Marie leave Kansas City by disguising themselves as Girl Scouts to get a train to New York.
