Dr. Strange (Benedict Cumberbatch) is a surgeon with superb IQ and superb skills. He is a legend in the hospital and even the entire medical community. One day, Dr. Strange suffered a terrible car accident. Although he saved his hands, his hands were trembling with scars, which meant that he could no longer pick up the scalpel and stand under the shadowless lamp. Dr. Strange's life lost its meaning and fell into despair. He decided to go to Nepal to find the legendary mysterious power that could heal his hands. In Nepal, the dusty Dr. Strange worshipped the mysterious Ancient One (Tilda Swinton) and became his disciple. At the same time, Casillas (Max Mikkelsen), the former disciple of the Ancient One, was also coveting, trying to complete his great cause of immortality.
