The series focuses on the lives of three Halliwell sisters, known as the Charmed Ones: Prue (Shannen Doherty), Piper (Holly Marie Combs) and Phoebe Halliwell (Alyssa Milano), as they deal with their grandmother's death and learn that they inherited a little more than the house they grew up in. All three of them have inherited magic powers; Prue has the power of telekinesis, Piper has the power to freeze time, and Phoebe has the power of premonition. Together they try to live everyday normal lives in San Francisco, while battling demons and warlocks, and keeping their supernatural identities a secret.
