While exploring the local area Jill discovers a small Chinese box in an antique shop and takes it home to add to her collection.

After being prescribed sleeping pills the nightmares seem to fade and Jill begins to relax. Then the waking dreams return, far more intense than before, blurring Jill's perception of reality.
