We all wish for the chance to go back in time and change things, and for The Flash, that chance is within reach. As a boy, Barry Allen had his life torn apart when his mother was a victim of a violent crime, but now, using his power of super speed, he will traverse time to change that fateful day. His intentions are good, but changing the past has repercussions that could prove disastrous, as a fractured, alternate universe now exists in place of the familiar one. Stumbling through a twisted reality where even Superman is nowhere to be found, The Flash seeks the trusted wisdom of Batman, only to find a grittier, more violent Dark Knight in his place. The Flash and Batman, with the help of Cyborg, race to restore the original timeline while the alternate world is ravaged by a fierce war between Wonder Woman's Amazons and the Atlanteans led by a battle-hardened Aquaman. With breathtaking action and an all-star voice cast featuring Kevin Conroy, C. Thomas Howell and Dana Delany, it's a bold, emotional vision that will forever alter the landscape of the DC Universe!
