The Halliwell sisters experience mixed emotions when their long-absent father, Victor (played in this episode by Tony Denison), returns. Things become even more strained when dear old dad aligns himself with some shape-shifting neighbors who would love to unlock the secrets of the "Book of Shadows" -- and will stop at nothing to do so. And in a plot development that will bear great significance on the episodes to come, Brian Krause makes his first appearance as studly handyman Leo Wyatt, to whom Piper (Holly Marie Combs) is immediately attracted. ~ Rovi
