Nicholas is another warlock after the sisters' powers. What makes him different is that he's immune to witchcraft, the result of a deal he struck with the girls' mother in return for sparing her life. When they seek guidance from the Book of Shadows they wind up in the mid-70s, and their task is nothing less than to change history. It's an emotional time for the girls as they meet not only their mother and grandmother, but in Prue and Piper's case their own young selves. (Phoebe is still in the womb.)
