John Grant is returning to Sydney after a year teaching at a one-classroom school in the Outback. Shortly after hitting the road, he collides with a kangaroo, and finds himself marooned in a small mining town, awaiting repairs on his car. With little to do but drink beer, John is seduced into a raucous, illegal game of two-up. After a short, exhilarating winning streak, he loses everything, which triggers a dangerous series of events that render John a broken and desperate man.

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.
