Gabriel Garrison's secret identity has been compromised. A mysterious anonymous letter promises to reveal he is Axiom-man unless he bows down to the sender's demands. And the timing cannot have been worse. Redsaw has become more powerful than when Axiom-man battled him on what has become known as Black Saturday, and he has determined to attain unstoppable power through the only means he knows how: murder. Chaos ensues and as the air is saturated with the stench of blood, Axiom-man must find the means to stop Redsaw before the whole world is swallowed in a web of death. Complicating matters, something strange is happening to Axiom-man's powers. The abilities he has put his faith in have changed. As time runs out and city streets are overrun with carnage and fear, Axiom-man is pushed to his breaking point as he tries to stop the madman's reign of terror, while also trying to discover what is happening to his powers and how they tie into a supernatural event that took place over five hundred years before.
