Ellie Andrews (Colbert), a mixed-up heiress, hits the road incognito to escape a chronically over-protective father (Connolly). Riding with the common folk on a bus, she meets reporter Peter Warne (Gable). After a bumpy start, he grudgingly befriends this unusual creature, who appears oblivious to the ways and customs of real working people. When Peter finally discovers her true identity, he knows he's got hold of the story of the century, but there's a slight wrinkle: the poor sap has begun to have feelings for Ellie. What's a desperate, smitten newsman to do?
