When word reaches Jason and his bandmates about several defectors who escaped Harlan Yates, the group realizes it's time to act. With their allies from Abaddon -- including the newly-turned demon, Daniel -- the band makes their move to get rid of Yates once and for all.
Led by the demons Gabriel and Haez, the others take the fight directly to Yates, aided by the defectors. Jason and his bandmates have never been in battle, and they're going to discover it's not for the faint of heart. Not everyone comes out unscathed, but that's the nature of war. For one of them, a single bite changes life forever.
