Synopsis by Rovi
The Charmed Ones discover that a band of rogue warlocks is capturing and enslaving the Muses. The sinister plan is to use the Muses' divine creative talents (singing, acting, writing, etc.) to create a new demonic faction in the absence of The Source of All Evil. Hoping to prevent this, Piper (Holly Marie Combs), Phoebe (Alyssa Milano), and Paige (Rose McGowan) must themselves risk permanent imprisonment to rescue the Muses and vanquish the warlocks. Meanwhile, Cole (Julian McMahon) is put out over Phoebe's reluctance to make a commitment, and he begins to wonder if giving up his demonic powers was such a hot idea after all.
