As the pair work on their adventure in the pages of the book, Piper, Leo, and Phoebe work on trying to finish the story themselves to bring Paige and Brody back to the present before they're killed by the story's criminal element.

Leo and the sisters are forced to protect the Seer when the Avatars insist she has valuable information about how to destroy a powerful group of demons, led by one called Zankou. The Seer then only agrees to help them gain the information they need if the Elders repay her by making her human. Paige and Darryl learn of what Kyle did to Inspector Sheridan. Piper finally learns of Leo's secret and contemplates the Avatars plan of creating a Utopian future.
