A copycat of the most famous murder in history...

A serial murderer nicknamed the Blood Dahlia has been terrorizing the quiet suburbs of Pennsylvania. Brutally mutilating his victims in the fashion of the most famous murder in Hollywood, the killer leaves no trace behind.

The FBI's elite Behavioral Science Unit, the section responsible for the study and investigation of serial murder, has little evidence on which to go. Believing the killer to be beyond their reach, the agents in the BSU decide they must simply wait for the killer to make a mistake, until they meet Sarah King.

Sarah, a mysterious outcast of the Pennsylvania Amish community, claims she has a unique ability: She can speak to the dead. And the victims of the Blood Dahlia are calling out to her.

When the FBI enlists her help, special agent Giovanni Adami is skeptical of her abilities but begins falling for the young woman. His feelings for her are clouded with his distrust of psychic phenomena, but as the Blood Dahlia grows in his barbarism, he knows the FBI has little choice but to explore every avenue available.

Whether or not Sarah can speak with the dead ultimately doesn't concern Giovanni. He is interested in results, and when Sarah begins providing some, he must question everything he knows about the world and his place in it. She is either the cleverest fraud he has ever met or a true psychic with an unexplainable gift.

But when the Blood Dahlia takes an interest in Sarah personally, it will take every ounce of strength she has to survive. As she prepares for him to come for her, she realizes not everyone is what they seem.
