It’s cosmic adventure on a grand scale as the Justice League faces off against Lex Luthor’s newly assembled Injustice Gang while the fate of the Earth itself hangs in the balance. To make matters worse the Justice League is informed that Luthor’s ultimate weapon, a mystic stone of incalculable power, must not be destroyed. And that’s just the beginning! Later in the far flung heroes of the 853rd century and the machiavellian manipulations of the vile god Darksied and the result is, quite literally, a race through time to put a stop to an evil that threatens all of existence!
