Vampires and homo sapiens have co-existed; sometimes living in peace and other times in violence. The on and off wars between vampires and homo sapiens has waged for centuries. Recent scientific discovers – DNA and archeology – proves that vampires are cousins of homo sapiens. When the vampire rebels drop their demand for a homeland for vampires somewhere in the Carpathian Mountains, the war officially ended with the signing of the London Peace Accords.

Most people hail the Accords and the peace it provides. However, extreme militants on both sides vowed to continue the battle. The two sides wage a terrorist campaign on each other, often killing innocent bystanders. In 2050, the FBI forms a task force as part of the anti-terrorist division to hunt down both extremists and prosecute them. Michael Castillo, a rookie FBI agent and a homo sapien, and Branko Renner, a former rebel vampire, are reluctant partners on the task force.
