Hi, Ruthy! I had it on but I'm afraid I didn't follow the plot too closely because I was trying to keep up with a few FR threads at the same time :) Here's a summary, though (BTW, if you click on the links below, there are summaries of the other episodes as well--including episodes they haven't shown yet on the second link!):

The psychic Mrs. Druse is called to assist when the trapped evil spirit of a tortured teenaged boy wreaks havoc on the staff, patients and innocent spirits inhabiting Kingdom Hospital. Meanwhile Dr. Hook forges a relationship of the mortal variety.
