Red Justice

The Justice League has been called to the Ural Mountains in Russia where a decaying nuclear reactor threatens to melt down. The heroes are able to shut down the reactor, but in doing so they also cut off the power to a long-forgotten cryogenic lab hidden deep under the mountains. A group of genetically engineered meta-humans frozen in the lab are revived. Code-named Red Dawn, they are endowed with powers that rival and mirror those of the Justice League. The Justice League has finally met its match-unless the Flash can save them in time.
