In the conclusion of a two-part story, Superman remains in limbo, even as his comrades and all mankind mourn his apparent death. By the time he makes it back to earth, the planet is in a state of ruin -- and it is all the handiwork of would-be dictator Vandal Savage and the diabolical "White Dwaft" device. Adapted from the comic-book story "Under a Red Son," Hereafter was intended to be telecast near the end of Justice League's second season, but was bumped forward because of its high suspense quotient. ~ Rovi
