On a different Earth than that of Gotham, the villains have won. They've grown, started families, and have ruled their earth for about twenty years. Just enough time for their children to grow... and rebel. After discovering an interdimensional threat, the children of Gotham's villains must travel to different Earths to warn them of the danger. After landing on an Earth with their coms and jumping technology fried, can they convince Gotham's heroes that they're on their side? And can they stop the threat before all who live in Gotham are destroyed?
