Dormammu, Lord of the Dark Dimension's conquest of the Earth is almost complete, with a stranglehold on the minds of its citizens. Only a few have managed to resist him... To free the world, Doctor Strange must reassemble his Shadow Avengers, while Tony Stark and a team of amoral tech geniuses cook up a tech defense to the mind control. As the Shadow Avengers defend Earth and against those heroes under Dormammu's influence, it's up to Ms Marvel to enter the Dark Dimension and enlist an unthinkable enemy - only Venom can help her destroy the evil sorcerer within.
