Reverse-Flash manipulates the Speed Force to put the Flash into a time loop that forces him to relive the same day over and over again—with progressively disastrous results, including losing his powers and being fired by the Justice League. The Flash must find a way to restore time to its original path and finally apprehend his worst enemy before all is lost for the Flash…and the world!

The Flash finds himself in a war-torn alternate timeline and teams up with alternate versions of his fellow heroes to restore the timeline.
