In the supermax prison called Iron Heights, the Flash's most dangerous enemy plans his escpe, dreams of revenge, and prepares to put the Flash on ice for good—driven by a personal grudge the Flash can't see coming.

And deep within the Flash himself, incredible new powers are ready to be unleashed—unforeseen, unexplored abilities fueled by the same Speed Force that makes the Flash run, and which could be his greatest weapon… or his worst nightmare.
