In The Lunch Witch, Grunhilda is the latest in a long line of witches who have "stirred up trouble in a big, black pot." However, nowadays no one believes in magic anymore, so despite inheriting her family's cauldron and recipes, Grunhilda has only found work as a lunch lady. This position is the best way for her to get in her scare quota, but she eventually finds a kindred spirit in a young girl name Madison, who is falling behind in school and doesn't fit in with her classmates. Grunhilda will soon find herself wanting to help Madison, even though helping others goes against everything she believes in as a witch. The original graphic novel was followed by Lunch Witch 2: Knee-Deep in Niceness, which could be made into a sequel should the first movie prove successful.
