Cape Perdido is a small town in Northern California which has a clear, cold water river held in Public Trust. The town's main industry once was lumber, but when Timothy McNear closed the mill, tourism became the income source. Now a group wants to siphon off a large percentage of Perdido's water every year to ship to Southern California. To combat this, the town has brought in ecologists and environmentalist Joseph Openshaw, a native of Perdido. But the strife leads to a murder and awakens secrets from the past.
