When the Flash breaks through space and time to reach a parallel Earth, it mirrors our own-except for one big difference: there is no Speed Force. Disconnected from the energy source that powers all super-speedsters, this is a world where The Flash never existed, and has become deadly for anyone who wears a mask. Powerless and hunted by the law, the only way Wally West can survive and escape is to accept help from those he trusts the least-his own Rogues Gallery!
