Country truck driver Jack Willis has written a romance novel but, fearing ridicule from his mates, he uses a pen-name, that of his long-time friend Ruby Vale, a local crop-dusting pilot. When he lands a book deal, the publisher sends out a vivacious publicist to convince their new novelist to come to Sydney for the promotion of 'her' new book. Jack's initial solution to the problem is to offer to pay for Ruby's wedding if she'll pretend to be the author. He soon realises, however, that the high-spirited Ruby is likely to run amuck in Sydney in her new role as romance writer, so he decides to escort her as her manager.
