During the roaring twenties, Jessie Miller flees a passionless marriage in Australia for London and the Bright Young Things. She meets Captain William Lancaster, married and fresh from the Royal Air Force with a scheme to outdo Charles Lindbergh: fly from London to Melbourne. And Jessie is the perfect co-pilot. Landing in Melbourne, Jessie and William are international celebrities and deeply in love. But the 1929 crash mixed with bootleg booze and scandal leads to a shocking crime, a trial that rivets the world, and a reckless act of abandon.
