There's trouble afoot at Grace Brothers! Someone's been lifting Mrs. Slocombe's skirts and putting their hands in Mr. Grainger's drawers. Shoplifting has struck the store and Mr. Rumbold installs a store detective and a video surveillance system. It goes off track for awhile, as Mr. Rumbold turns into a voyeur and the staff act like they're on television. Ultimately, the staff decide to do in the scheme and prey on Mr. Rumbolds hypochondria to accomplish it. (thetvdb.com)
