It's 1922. Prohibition is the law of the land. A rumrunner's boat is found adrift near the United States-Canada maritime border of Puget Sound, its crew missing, its cargo hold riddled with bullet holes and awash with blood. Young Sheriff Miles Scott—traumatized by his experiences in World War I and obsessed with protecting his remote, Eden-like island community—takes on a murder investigation with a list of suspects including rival rumrunners, temperance fanatics, anti-immigrant labor leaders, and the hatchet men of Seattle's powerful underground crime syndicates. Contending with a hidden array of informants and corrupt officials, Miles races against a killer who continues to spill blood to cover his tracks.
