Black Adam and the Eternity War

When the undead arise to engulf the world, the Justice League — with the help of Billy Batson and his heroic alter-ego SHAZAM — leaps into action. They soon discover Black Adam in control of the Rock of Eternity and are quickly banished to ancient Egypt. Can the Justice League fight their way back from the past to defeat the super-villain in time? Or will Black Adam go unopposed as the conqueror of all eternity?
