On the day of Piper's marriage to Leo, Prue's Astrally Projected-self adopts an uninhibited, wild personality that threatens to ruin the wedding and place Prue in jail for Murder.

Looking for a little privacy now that they're married, Piper and Leo decide to move out on their own. As a result, the sisters have to come to terms with how things now are, and then they reminisce about how things were after Grams died and when Phoebe moved to New York. As they're dealing with the possibility of Piper's possible move, the sisters have to battle a warlock who was a former cat multiple times before being able to vanquish him before he turns immortal.
