When a bridge in the small outback town of Mululuk mysteriously collapses, the town is cut off from the world, and its citizens from each other.
As the locals try to work out why the bridge fell and what it will take to replace it, old rivalries, forgotten romances and primitive drives come to the fore. Teenaged Rachel has come from ‘the city’ to stay with her uncle after her home life has fallen apart, and she quickly becomes involved in the quest for the truth about the bridge.
Father Nott, the local Franciscan priest, is trying to get the hysterical townsfolk to see sense, particularly his gossip-mongering friend Gussy. Shane, Janice and Craig find themselves at the heart of a devastating love triangle, with deadly ramifications that will reverberate far beyond the three of them.
And the mysterious Charlie, a scruffy, charismatic alcoholic with a dark past, has a terrifying idea about what it takes to keep a bridge standing. In a town that keeps its secrets like it builds its houses – underground – Charlie’s is the most dangerous of all.
