The new head of men's department is introduced and the staff prepare for a possible royal visit.

Young Mr. Grace invites his workers to form a social club - in a dismal cellar badly in need of decoration. Undeterred, the staff tackle the paint and paper job with vigor.

Mrs. Slocombe thinks she's finally got her man, a bouzouki player in a Greek restaurant. The staff plan a reception at the store to help keep costs down, and her American uncle plans on giving the happy couple a house. Before they can leave for the church, however, the best man arrives with bad news, forcing Mr. Tebbs to don the garb of a Greek vicar and Mr. Humphries that of the bridegroom.

Sales figures are down; profits are low. Young Mr. Grace is forced to make some economies. The threat of redundancies is looming. Someone is going to have to go - but who is it to be?

A new display of perfume arrives from Bliss, but there is no Bliss Girl to man the counter. Mrs. Slocombe refuses the position, so Mr. Humphries becomes the Bliss Girl for the day.

It is Young Mr. Grace's birthday, and the staff sing the traditional birthday song for him and enjoy the traditional free lunch. They later rehearse their cabaret performance for Young Mr. Grace's birthday party, a ballet called The Ballet of the Toys. A professional cabaret troupe will also be performing at the party, and when the troupe arrives, it turns out they themselves will be performing The Ballet of the Toys, which forces the staff to go to Plan B.
