Guided by visions of La Pucelle (the name given to Joan by followers), Emil seeks to unite France under the divine rule of the King. In her quest, Emil goes to the same places Joan had traveled through, and gains her own followers in the process. However, Emil is opposed by the dauphin Louis, a brute enforcer who fears no divine power and wishes to make his own bid to rule the country.
