Charmed: We're Off to See the Wizard on AllMovie

Piper (Holly Marie Combs) and Paige (Rose McGowan) pool their powers to prevent the coronation of the new Source of All Evil. They are still blissfully(?) unaware that the soon-to-be Source is their own brother-in-law, Cole (Julian McMahon). As for Cole's wife, Phoebe (Alyssa Milano), she has no idea that she is slated to be Queen of the Underworld; all she knows for sure is that she is pregnant, and that Cole is the father.
