The media has dubbed River Kelly the Red Devil after she assaulted a local biker at a popular bar. Armed with a deadly, ancient weapon called the Azure Blade, River won't stop until every member of the Road Barons is slain.

With his psychic abilities fading, Cody Savage searches for River before she causes more chaos. As her attacks grow more brutal, Cody learns the truth about the Azure Blade, and if it falls into the wrong hands, worse danger will surface.

Meanwhile, Daisy Torrez convinces Jeff Bourbon to help her locate Flesti Thaed deep in the southern woods. Once they realize they are not alone, it might be too late, and if they make it out alive, the fate of Cain Lake will be changed forever.
