Scheduled to marry a man she doesn't love (and for good reason), spoiled heiress Barbara Blanchard (Claire Trevor) runs away from her wedding and hits the road. While hitchhiking, Trevor is given a ride by Bob Reynolds (Michael Whalen), a personable young auto salesman who's been hired to deliver what was then called a "caravan car" but would now be labelled an RV. As luck and the screenwriters would have it, a fugitive jewel thief hides his stolen gems in Bob's vehicle. Our hero is arrested, causing Barbara to cease her incessant put-downs of the poor guy. In trying to spring Bob from jail, Barbara realizes that she's fallen in love with him (why didn't she just ask the audience, who knew it all along?) It's positively awe-inspiring how many runaway-heiress films were spawned by the freak success of It Happened One Night.
