Country truck driver Jack Willis has written a romance novel. Fearing ridicule from his mates Jack uses a pen-name, that of his long-time friend Ruby Vale, a local crop-dusting pilot. Trouble brews for Jack when he lands a book deal with a publisher who sends out a vivacious publicist to convince their new novelist to come to Sydney for the promotion of 'her' new book. An offer to pay for Ruby's wedding soon convinces her that the favour is worthwhile. Jack realises that he can't permit the high-spirited Ruby to run-a-muck in Sydney in her new role as romance writer, so he decides to escort her as manager. Their relationship begins to take unexpected turns.
