Batman's greatest rival, Ra's al Ghul continues his quest to save Earth from humanity by thinning the ranks of the human populace. But after being thwarted over and over again, Ra's seeks to distract Batman by stealing the bodies of his dead parents while he enacts his nefarious plot. And to insure that Superman, Wonder Woman, Green Lantern, the Flash and the rest of the JLA do not interfere with his plans, he individually defeats each of the heroes using strategies developed by Batman himself! And when the League learn of his betrayal, they look to expel the Dark Knight from their ranks.
