Synopsis:
The Mirror Master invents a new mirror which can see 20 seconds into the future. The new ability gives the crook an advantage over his nemesis, the Flash. Flash then decides to travel three days into the future where he locates the Mirror Master's hide-out. Mirror Master's mirror predicts that Flash will be disintegrated by his weapon.

When the scene plays out just as the mirror predicted, the Mirror Master believes he has killed the Flash. However, Flash merely stopped his internal vibrations and returned to the time three days earlier. Then he waits three days for the events to play out. Flash watches as Mirror Master gloats over his victory, then appears and captures his foe, destroying the special mirror in the process.
