700 years ago, a battle had been fought in Asia Minor over a magic staff called Skulkane that can summon a demon called Dormammu on a full eclipse. The rod is broken in half. Many years later, surgeon Stephen Strange has his hands mangled in a car accident. He heads to Tibet to reach the Ancient One. From there, Stephen must use his newfound powers to stop former disciple Baron Mordo from reuniting the two halves to create the ritual of Dormammu once more!
