Homicide inspector Gavin Cain is standing by a grave when he gets the call. Cain knows there's something terrible in the coffin they're about to exhume. He and his team have received a dying man's confession and it has led them here.
Cain is summoned by Mayor Castelli, who has been sent sinister photographs of a woman that he claims he doesn't know and a note threatening that worse are on their way.
As Cain tries to identify the woman in the pictures, and looks into the mayor's past, he finds himself being drawn towards a situation as horrifying and as full of secrets as the grave itself.
