In medieval France, the powerful witch Maria aims to stop the never-ending battles waged between England and France in the Hundred Years War using any means necessary.

If it will put a stop to the needless slaughter, she'll use all her magical abilities to summon basilisks, golems, and even succubi - despite the fact the she herself is actually a virgin. But the Kingdom of Heaven will not standby as a witch interferes with the lives of men, and the Archangel Michael punishes Maria for her folly, cursing her to lose her powers if she is ever to lose her virginity.

Maria must then make a choice - she needs her powers to stop the war, but to keep her power, she must never taste the forbidden fruit of adulthood.
