In the conclusion of a three-part story, the Justice Leaguers, teamed with an alternate-reality Vandal Savage, have gone back in time to World War 2 in hopes of preventing the present from being horribly altered by despotic dictator Vandal Savage. Assisting the League in its efforts are such vintage comic-book heroes as Blackhawk, Steve Trevor (Wonder Woman's erstwhile mortal beau), and Sgt. Rock of Easy Company. Unfortunately, the villainy has been doubled as the 1940s-era Savage trades information with his modern-day counterpart. Will the combined forces of good be able to vanquish Savage, or will the horrifiying "alternate" world of the 21st century become reality? ~ Rovi
