Paige (Rose McGowan) is transported back to 1969, at the height of the "flower power" era. Here she finds that the younger version of Penny "Grams" Halliwell (Jennifer Rhodes) is an oh-wow hippie (Kara Zediker) who hopes to use the power of love to expunge the world of evil -- and hang the consequences! Meanwhile, back in the present, Phoebe (Alyssa Milano) and Piper (Holly Marie Combs), their powers diminished by Paige's absence, must face the challenge of a magic-devouring slime beast. And Whitelighter Chris (Drew Fuller) continues exhibiting reluctance and resentment while carrying out his assignment to protect baby Wyatt. ~ Hal Erickson, Rovi
