Three cute wood nymphs lose their satyr-protector to a demon who demands that the girls show him the "eternal spring" of immortality. In trying to help the enchanted threesome, Paige (Rose McGowan) is herself transformed into a nymph -- and she may not be allowed to reassume her human form. Elsewhere, the Charmed Ones squabble over new witchcraft issues, and Phoebe (Alyssa Milano) wonders if her relationship with her handsome boss, Jason (Eric Dane), is truly spiritual or merely sexual. ~ Rovi
