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.

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.

Sales are falling once again and so Mr. Rumbold calls together a "think tank", a suggestion he "borrowed" from Captain Peacock. The staff decide that a fashion show would be the answer, but when Young Mr. Grace won't cough up the dough to hire proper models, the staff are forced to put on the show themselves.

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.
