Synopsis:
The JSA have been missing for over a year with crime rampant and the threat of World War 3 a possibility. The tale begins a year before when the JSA was summoned by Professor Matthews to Africa. From him they learn the story of four ancient kings of a super-race, and they follow the Professor to a cavern containing a vacuum glass case holding the kings in suspended animation. The case is broken, releasing them...but the king's mental commands put the JSA into a year-long sleep. Returning to Civic City, they read of four leaders of new war parties, so the JSA splits up to tackle them.
