Whut? ? ?
If you've never heard of Charmed, here's a brief explanation.
After the death of their grandmother, Prudence (Shannen Dougherty) and Piper (Holly Marie Combs) move into her house. They are joined by youngest sister Pheobe (Allysa Milano). On Pheobe's first night there, she goes into the attic, and finds a trunk with a large book called "The Book Of Shadows".
She reads an incantation on the first page, and discovers that she and her sisters are witches, destined to be "The Charmed Ones", three powerful witches who protect the innocent from demons, each sister with a specific power.
Prudence can move objects with her mind, Piper can freeze time, and Phoebe can see the future.
