Perth, 1977. Mary Patterson stands at the side of the road with her thumb out and a suitcase at her feet. She's leaving everything behind. A kind stranger offers her a ride across the Nullarbor. Adelaide is two thousand kilometres away. Far enough to start over. Far enough to be free.But freedom is a long, straight road with nowhere to hide.As the empty highway stretches endlessly before them, Mary begins to see things. Or remember things. The line between past and present blurs. And the man driving starts to look like someone else.Someone Mary has been running from her entire life.
