Charmed: Cat House on AllMovie

Beset by domestic problems, Piper (Holly Marie Combs) finds herself unable to control her magical powers. In an effort to help her sister, Phoebe (Alyssa Milano) consults a marriage counselor -- but when the counseling session proves to be too slow and laborious for Piper, she impulsively casts a spell to speed up the proceedings. The result: Phoebe and Paige (Rose McGowan) are hurtled back in time, where they are forced to experience all the memories, both good and bad, of Piper and her husband, Leo (Brian Krause) -- enabling the series' producers to superimpose new footage upon clips from previous episodes! Complications ensue when a malevolent warlock hitches a ride on Phoebe and Paige's foray into the past.
