L.A. County Sheriff’s Detective Stilwell has been “exiled” to low-key Catalina Island. But while following up the usual drunk-and-disorderlies & petty thefts that come with his new territory, he gets a report of a body found weighed down at the bottom of the harbor. At the same time, a report of poaching on a protected reserve turns into a case fraught with violence & danger as Stilwell digs into the shady past of an island bigwig.
