Grace Brothers hosts a week long sales event by selling only German goods. The staff, however, find that the German customers they are getting only want British goods. Captain Peacock objects to the "uniform" he's expected to wear and Mrs. Slocombe gets into the German wines.

The Department figures have taken a dive and so Mr. Rumbold decides to convene a sales conference amongst the staff. Since the meeting is taking place after hours and off the clock, no one is very motivated to provide any solutions. If something isn't done, someone might lose their job, and that someone is clearly Mr. Lucas.

Rumors fly when Captain Peacock gets too friendly with Mr. Rumbold's secretary at the Christmas party, and things get really out-of-hand when it seems they might have spent the night together.

A reorganization within the store forces the staff of the gentlemen's ready-to-wear department to share their floor space with the Ladies' Department. Mrs. Slocombe, head of the Ladies, and Mr. Grainger, head of the Gents, immediately come to loggerheads over control of the center floor display. Mr. Grainger refuses to take down his trousers and put Mrs. Slocombe's underwear in its place. Undaunted, she goes over his head to Captain Peacock, and then to Mr. Rumbold.

When Mr. Grace announces that he plans on temporarily reorganizing the departments, the staff are indignant, but find that work can be a lot of fun...if you're working in the toy department.

The staff must take physicals to get insurance. Listening through the door of Mr. Grace's office, they hear Mr. Harman describing the state of the furniture, which they misunderstand as being the results of their physicals.

By permission of Mr. Grace, Mrs. Slocombe moves into a display apartment in Grace Brothers, because her new home is occupied by squatters. Due to a transport strike, Mr. Humphries seeks to join her in her new accommodations.

A transport strike leaves the staff stranded at the store, so Young Mr. Grace offers to let them spend the night on the floor. Tents are set up, but Mr. Lucas has trouble keeping his up. A "campfire" sing along leads to talk of the last World War and the experiences some of them had.

A fuel shortage grips the country and Grace Brothers, so the stores furnaces are shut down for the day. The staff are freezing and soon develop unique ways to keep warm.

Mr. Grainger is selected to fill in for Mr. Rumbold while he is away; the staff wonder whether they should take advantage of Mr. Grainger's good nature, only to discover to their horror that he doesn't have one when he sacks Mrs. Slocombe.

The staff star in a TV commercial for Grace Brothers, produced by Mr. Humphries. Could Mr. Grace's cheapness be the reason for using his staff in such fashion?

It's Mr. Grainger's 37th anniversary at Grace Brothers and the Department hosts a celebration dinner for him. It's a time of happiness, and dread, for if he receives a cuckoo clock then it means he's to be retired.

After Mrs. Slocombe starts dropping hints that it's her birthday, the staff calculate that she is 50 and plan an appropriate party.

Young Mr. Grace returns from a trip to the U.S. with a host of new sales techniques that he is eager to implement.

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.

When Mr. Grace decides to open the store early, the staff set out to sabotage the new policy.

Mrs. Slocombe temporarily takes the place of Mr. Rumbold, who has taken ill . She eats the cream cakes she finds in his office. But she then gets a call from the hospital warning that the ice cream is what made him ill.

Mr. Grace has an idea to improve Christmas sales--all the staff are to wear novelty costumes, much to their annoyance.

The staff have kittens when Mrs. Slocombe announces she's expecting a happy event, but it turns out that it's merely her cat that's pregnant; when she refuses to leave Tiddles unattended, she braves the ire of Captain Peacock by smuggling the cat into the ladies' fitting room.

The staff prevent another firm's hostile takeover of Grace Brothers by impersonating the shareholders. Mr. Harman gives a rousing speech, and Grace Brothers is saved.

Mr. Grainger's temper has become extremely short. The staff, in a private meeting with Mr. Rumbold, decide he must go. However, when he wins the lottery, his bad mood vanishes and he makes his peace with the staff and stays on.

Mr. Grainger's trousers are missing, along with the central display. The staff learns that the space was freed up for the "His & Hers" fragrance display. Mrs. Slocombe is outraged that they went her to take down her underwear and put perfume there in its place. The glamorous salesgirl causes stirrings in the trouser department. When it's discovered that free stockings and ties are given out with every scent purchase, both departments formulate a plan to oust the intruder.

The Store's redecoration plans threaten to interfere in the staffs vacations. Everyone is now expected to take the same two weeks off and there's disagreements on how to handle it. Grace Brother's Tour Group Company offers some package deals, but they are far from First Class.

Mr. Grainger is 5 minutes late coming back from his coffee break and this sets in motion a management scheme to monitor all breaks. The staff must sign in and sign out when they leave and return to the department. The department staff revolt and union action is taken

The Ladies Department is temporarily closed due to refurbishing, so Mrs. Slocombe and Miss Brahms are given counter space over in the Gents. However, the men aren't very happy at having to share their area and do their best to make them unwelcome.
