Rex is a loner, and when he's told he doesn't have long to live, he embarks on an epic drive through the Australian outback from Broken Hill to Darwin to die on his own terms; but his journey reveals to him that before you can end your life, you have to live it, and to live it, you've got to share it.

In 1929 Arthur Upfield, Australia's premier crime writer, plotted the perfect murder for his novel The Sands of Windee. Meanwhile, one of his friends, stock-man Snowy Rowles, put the scheme into deadly effect, even before the book was published. This true story resulted in one of Australia's most sensational murder trials of the 1930's and catapulted Upfield's name onto the world stage.
