Once the institutions of his world proved untrustworthy, a young veteran leaves college and seeks refuge in a shack beneath a condemned train bridge along the depleted and abused Salt River. Here, he encounters those society deems invisible: Natives, migrants, and discarded souls. A makeshift clan forms as curious individuals are drawn to this enigmatic figure and his humble dwelling. Among them are a compassionate female doctor, a questioning priest, a lonely flour mill guard, a seventeen-year-old girl yearning for freedom, and a disheartened judge. Even scorpions, black widows, and countless butterflies find their place. To the Salt Shack Dweller, this motley group becomes a true family.
