Opening narration: "The human mind has been compared to a house -- it's rooms filled with memories, ideas and dreams. Rooms which remain essentially locked and inaccessible. But what if we could make a master key?"
The sanity of a doctor is challenged when she uses herself as a guinea pig to test a psychological tool allowing her to enter her patients' minds.
Closing narration: "If we are going to delve into the true secrets of the human soul, we must be prepared to deal with the demons that reside there."
