Witchstock

When Paige finds an old pair of go-go boots that Grams owned, she gets transported back to 1967. Upon arriving there, Paige discovers she fits right in, since magic is practice freely and that was a dream of hers. However, Piper and Phoebe have their work cut out when they try to find a way to keep Paige from changing their timeline, only to discover they're the ones that cause damage in the past.
