Liv Durant inherited a winery in the Napa Valley and left her job as the Director of Interrogations at the San Francisco office of the FBI. She helps out as a consultant to the Napa County Sheriff and the FBI on cases to keep her hand in the game of cops and robbers from time to time. Her late husband Robert, was killed in a helicopter crash ten years earlier when he was a member of the FBI Hostage Rescue Team, or so the story goes. Liv didn't believe it for a second. A drug case in Napa drags her back into the middle of the action and brings a new friend, Beckett Donovan, as the FBI liaison official into her life. Donovan also happens to be Robert's old partner with revelations into the truth about Robert's death. The case expands as the investigation moves along and may bring down the whole San Francisco mob.
