One day, Sophie, a young milliner, was recused by the wizard Howl when she was entangled in the soldiers.
At the same time, Howl was also being chased by the "Witch of the Wasteland" who was aiming for him. Sophie was transformed into a 90-year-old lady by the curse of her witch.
Sophie can no longer stay in the hat shop and leaves home. On her way, Sophie helped a living scarecrow "Turnip Head" in the wasteland. After that, he brought her to Howl's moving castle.
There was Calcifer, the devil of fire, who was forced to use magic to move the castle. He made a deal with Sophie, agreeing to break her curse if she helps break his link with Howl. Therefore, Sophie tells Howl that she will be a castle cleaner and live in the castle.
Although Howl yearns for a free and easy life, he is often asked by the king to fight and go to the battlefield. Howl also has a secret that puts him in danger.
Can Sophie save Howl? Also, can Sophie return to her original face?
