Synopsis
In the world of the 31st Century and the city of New Modernia, a shape-shifting race called the Chameleons have appeared, and they are so great a peril to society that Professor Ellery approaches the Mayor and City Council. He proposes that he take a Time-Bus back to the 20th Century to get the Justice Society involved in the matter and bring them back to the 31st Century. The JSA, after having encountered a Chameleon, agree.
