Addie's older sister Nina gives her a makeover. Later, when Addie gives a speech in front of the town council, she is heartbroken to find that her new best friend Audrey, who promised to support her, doesn't show up to hear her speech.

Addie and Audrey solidify their friendship when they go door to door to spread the word about the women who were wrongfully accused as witches. To heal the rift between her twin sisters, Addie plans a party for their upcoming birthday.

Despite Mr. MacIntosh's strict rules about using the town hall and Miss Murphy's attempts to shut it down, Addie’s birthday party for Nina and Keedie is a success. But when Addie's bully Emily crashes the party, things take a downward turn.

Keedie avoids her new friends out of fear they'll treat her differently if they know she has autism. Addie's fundraising campaign disrupts a beloved town event, which turns into the opportunity Miss Murphy needs to take control of the town council.

Addie's fate at her school is decided. Audrey and Frank discover the amazing story of Lady Margaret's escape, inspiring Addie to make one final plea to the town for a memorial for young women wrongfully accused as witches.
