Worlds collide when the Flash (Ezra Miller) uses his superpowers to travel back in time to change the events of the past. However, when his attempt to save his family inadvertently alters the future, he becomes trapped in a reality in which General Zod (Michael Shannon) has returned, threatening annihilation. With no other superheroes to turn to, the Flash looks to coax a very different Batman (Christian Bale) out of retirement and rescue an imprisoned Kryptonian Supergirl (Sasha Calle) captured by Batman's Rouges Gallery The Joker II, Bane (Tom Hardy), Deathstroke (Joe Manganiello) and Scarerow (Cillian Murphy) -- albeit not the one he's looking for.
