USA, 2010. Criminal genetic experiments in a U.S. military laboratory get out of control, and an artificially created virus breaks free. Those infected with the virus stop being human—they want only one thing: to kill. The main character is a former officer of the Delta unit, and his brother, one of the scientists who were at the origins of these experiments, are trying to survive and understand what’s happening. Almost immediately they realize none of this is accidental—that an epidemic of such catastrophic scale couldn’t have been accepted without outside help. And the war begins—a war for survival.
