Quentin Marshall has spent his life running from the trauma of his past. But when his estranged and abusive uncle dies under suspicious circumstances, Quentin is pulled back into the darkness he desperately tried to escape. Alongside vintners Frank Noir and Lydia Hartwell, he must confront the ghosts of his childhood and unravel a web of deceit that threatens to consume his entire family.

Meanwhile, Frank and Lydia discover an old house not far from the estate, which is rumored to contain hidden treasure. Opportunists arrive, seeking fortunes within the home that was formerly owned by Quentin's irresponsible relatives, and wreaking havoc on the tranquil lifestyle that Gray Estates so famously offers.
