Rex, a Broken Hill cab driver, has spent his life avoiding getting close to people. Even his best friend and occasional lover Polly, who lives across the road, is kept at distance. One day, he discovers he is dying. He doesn't want to be forced to rely on anyone, least of all Polly, so he decides to leave his home and drive alone the 3000kms across the continent to Darwin, where the recently passed euthanasia laws lead him to believe he can be in control of his own death. But on this epic journey he meets people who force him to re-evaluate his life. He begins to realize that a life not shared is a life not lived. Sadly it seems wisdom has come too late, until Polly finally gives Rex the courage to act. Against all the odds, in one final heroic act of pure will, he drives his cab back through time and distance to Broken Hill, where he will share what he has left of his life with the one he loves.
