Piper, Phoebe, and Paige learn that a warlock is in the process of kidnapping and enslaving the muses inside a special ring in order to make the forces of evil more powerful. As a result, they have to find a way to save the remaining ones and rescue the others before the warlock's plan comes to fruition. Meanwhile, Cole starts to get frustrated that Phoebe has so far spurning his marriage proposal and is worried that without his demonic powers, he'll be unable to help keep her safe from the demon factions who plan on attacking the Charmed Ones.

Phoebe is selected to serve on the jury of a man on trial for murder. During the case, she has a premonition showing someone else committing the crime, despite the evidence against the defendant. While Leo, Piper and Paige rush to find the rightful killer and bring him to justice, Phoebe does her best to stall her fellow jurors from finding the man guilty. Meanwhile, Paige's friend Glen is in town and Paige invites him to stay at the manor. While there, he discovers the Book of Secrets and soon finds out Paige's magical powers.
