In the aftermath of Earth's destruction in the 30th century, the shaken and weary survivors struggle to start a brave new world within the domed cities of New Earth. With the Legion of Super-Heroes having departed for deep space, another group offers the citizens of New Earth a symbol of hope in this turbulent time. From the ruins of Metropolis, a certain clubhouse is salvaged; new outfits are donned; new code-names are chosen; new members are admitted; old traditions return...and the Legionnaires are born.
