The story of Charmed begins with the three Halliwell sisters — Prue, Piper and Phoebe — that come together six months after the death of their maternal grandmother. After thinking about it, the three girls decide to move back into their family Manor in San Francisco. While snooping around, the youngest sister, Phoebe, discovered an old book — the Book of Shadows — in the attic. Reading an incantation from it, she unwittingly set in motion events that fulfilled an ancient prophecy. Strange and harrowing occurrences began which eventually led the sisters to realize that they are witches.
