Jack Willis is a handsome truck driver with a secret - he has just become a top-selling romance novelist. However, being a 'man's man' in the Australian outback, he needs a pen name, a woman's name - and he chooses the name of his best friend, Ruby Vale. He must do some fancy footwork to continue the charade when the glamorous city publisher, Ziggy, arrives to sign 'Ruby Vale' to a major book deal. Ruby agrees to help Jack though it's for her own gain as well - the publisher will pay for her coming wedding (to Hamish, Jack's buddy). Accompanied by Jack, Ruby goes to Sydney to meet the media, appear on TV and cocktail parties. Gradually, Jack realizes he has fallen for Ruby, while Ruby realizes she is touched by Jack's novel. Hamish meets them in Sydney and asks them to stop the charade, but it may be too late!
