Retired from active duty, and training recruits for the Impossible Mission Force, agent Ethan Hunt faces the toughest foe of his career: Owen Davian, an international broker of arms and information, who is as cunning as he is ruthless. Davian emerges to threaten Hunt and all that he holds dear -- including the woman Hunt loves.

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.
