"Two worlds, two sides, and both fighting the same evils, and never coming into contact… before now. In late August, Dean Winchester awoke in the middle of a cemetery in southern Texas, with no memory of how he escaped from Hell. Both the hunters and the slayers of the world are fighting a battle against evil, as well as a government that believes Buffy Summers' army will attempt to take over the United States, and soon, they are about to collide."
