Prue's (Shannen Doherty) sinister boss, Rex Buckland (Neil Roberts), and his confederate Hannah Webster (Leigh Allyn Baker) demonstrate anew that they can't be trusted as far as they can be thrown when warlock Matthew Tate (Billy Wirth) is released from a centuries-old curse. With Rex and Hannah's help, Matthew schemes to steal the "Book of Shadows" from the Halliwell girls, whereupon he will destroy their bloodline for all time. Tyler Layton makes a guest appearance as 300-year-old witch Melinda Warren, a very significant person in the lives of the Halliwells -- not to mention the demonic Matthew Tate's spurned sweetheart. ~ Rovi
