The staff return from their holidays, and Mr Tebbs has replaced Mr Grainger as Head of Men's Wear. After Captain Peacock returns sounding like Donald Duck and Mr Lucas with burnt feet, the staff are soon told that the Queen and the Duke of Edinburgh are making an official visit to the borough, and they might be coming to Grace Brothers. The staff rehearse what to do if the Royal couple visit and on the day they all dress up in their finery and then watch them in the street below from Mr Rumbold's office window. Unfortunately, just as it appears the Queen and Prince Philip might be about to enter the store, Mrs Slocombe accidentally knocks a plant pot off the window ledge which narrowly misses the Royal couple, who get back in their car and speed away from the scene as quickly as possible!
