Worlds collide when Barry Allen uses his superpowers to travel back in time in order to change the events of the past.
But when he inadvertently alters the future, Barry becomes trapped in a reality in which General Zod has returned, threatening annihilation, and there are no Super Heroes to turn to.
That is, unless Barry can coax a very different Batman out of retirement.
