"These walls have watched the witches;
the witches have watched the world.

The one thing that the Halliwell sisters have always been able to count on is their house, Halliwell Manor. It's a historical landmark in San Francisco, but to them it's more than that -- it's sheltered Halliwell women for generations. So when the Manor suddenly turns against them, wreaking havoc and playing tricks, the Charmed Ones have no idea what to do. The entire house has begun to exhibit demonic qualities -- it's almost as though it's come to life, with evil intent. Can they find the source of this house gone wrong before it vanquishes them?
