When his attempt to save his family inadvertently alters the future, Barry Allen becomes trapped in a reality in which General Zod has returned and there are no Super Heroes to turn to. In order to save the world that he is in and return to the future that he knows, Barry's only hope is to race for his life. But will making the ultimate sacrifice be enough to reset the universe?
Determined to ensure Superman's ultimate sacrifice was not in vain, Bruce Wayne aligns forces with Diana Prince with plans to recruit a team of metahumans to protect the world from an approaching threat of catastrophic proportions.
Ever since US Diplomatic Security Service Agent Hobbs and lawless outcast Shaw first faced off, they just have traded smack talk and body blows. But when cyber-genetically enhanced anarchist Brixton's ruthless actions threaten the future of humanity, they join forces to defeat him.
Fuelled by his restored faith in humanity and inspired by Superman's selfless act, Bruce Wayne and Diana Prince assemble a team of metahumans consisting of Barry Allen, Arthur Curry and Victor Stone to face the catastrophic threat of Steppenwolf and the Parademons who are on the hunt for three Mother Boxes on Earth.
