Calder (Vin Diesel) is a witch hunter. Under the curse of the Black Witch, he got an immortal soul and an immortal body. The pain of eternal life is far greater than the joy. In loneliness and despair, Calder spent a long time. However, he never gave up his duties as a wizard hunter. He knew that witches were not extinct, and a huge conspiracy was slowly brewing in the shadows. Sure enough, the Black Witch got the secret technique to resurrect herself. At the same time, witches everywhere could not bear it and were ready to move in an attempt to realize the ambition of destroying human beings and ruling the world. Calder and his assistant Dolan (Elijah Wood) want to face complex and powerful opponents, and must be helped by the kind witch Chloe (Rose Leslie). A fierce battle is about to begin.
