Wedding plans are in full swing in Bloody Mary, Virginia. J.J. Graves is ready to walk down the aisle and start a new life - despite the fact her father is still on the loose, blood money is stashed in her closet, and an unidentified body is missing from her parents' bunker.

But it isn't her personal life that's threatening her chance to say "I Do." It's the remains of a family of four that were killed in an ordinary house fire. But once JJ and Jack start investigating, they find there's nothing "ordinary" about murder.
