In 1990s England, a witch leaves her child, Earwig, at St. Morwald’s Home for Children. The matron head of the home thinks that the name is unfit for a child and changes it to Erica Wigg. Years later, Earwig is a rambunctious 10-year-old who is very comfortable in an orphanage where everyone does what she wants. She likes living there with her friend Custard and doesn’t want to get adopted. One day, a strange couple, Bella Yaga and Mandrake, adopt Earwig against her wishes. When they get home, Bella Yaga tells Earwig that she is a witch, and that she only adopted Earwig for “an extra pair of hands” to help around the house. Earwig agrees to help, only if Bella Yaga teaches her magic in return. Earwig prepares ingredients for spells and cleans the workroom. Tired of working, she attempts to get out of the house, only to find that all the exits have been magically sealed by Mandrake. She becomes further frustrated because Bella Yaga never teaches her magic.
