The Heavenly Hosts have declared that as Hell's most prominent ambassador to Earth, Blue Devil must be killed. Zauriel, the Angel and former Justice League member, has been dispatched to see Heaven's will is carried out. But once he understands the situation, to Zauriel's surprise, the Blue Devil accepts Heaven's judgement. Because of his unusual level of cooperation, Zauriel judges that they have a few days' grace period before the judgement must be carried out. Not wanting to die, Cassidy begins to see what steps he might be able to take to save not only his life, but also his immortal soul.
