Charmed is about Prue, Piper, Phoebe and Paige Halliwell.
They are the Charmed Ones, the most powerful witches ever. Together they have the power of three. With the help of Piper's husband Leo, who is now an elder, and Darryl, a police officer and a good friend of the Charmed Ones, they protect the innocents against demons, warlocks and other things of darkness. After Prue was killed by a demon, Phoebe and Piper found out they had a half-sister called Paige. With her help the Power of Three is complete again.
