Giulia Driscoll's sister-in-law barges into Driscoll Investigations and promptly passes out from OD'ing on an unknown drug. Two OD'd teenagers are found dead in the park and behind a convenience store. DI's new client insists her missing twin sister is not dead and enlists Giulia as the "Missing Person Whisperer." Hooray for steady work? The missing sister's trail leads to married, pregnant, ex-nun Giulia's first experience with online dating sites, to the delight of her husband and employees. Those dates lead her to local Doomsday Preppers. They grow their own everything, and that everything may be connected to the drugs, her sister-in-law, and the missing twin. These Preppers are about to learn the true meaning of doom.
