The JLA (Justice League of America), the world's greatest heroes, and the JSA (Justice Society of America), the original super-team, have joined forces time and time again to save the Earth in times of crisis. But this time, they face a challenge greater then any they've ever known - a challenge from within their own ranks! When villains from the rich histories of both groups hatch an insidious scheme that lays waste both the teams and the world they defend, what begins for the heroes as a friendly get-together degenerates into a destructive melee - and from the ashes rises a villainous uber-team, made up of select members from each group. But what has made these agents of virtue turn to agents of vice? And can the remaining heroes save the day - by defeating their friends?
