Among young scions of the upper class cutting their teeth as agents at a brokerage firm, Nigel and Giles share a flat, as well. Nigel, much like Beverly in Abigail's Party, becomes consumed with plans for a dinner party, but can't seem to convey the importance of the occasion to Giles, who is perpetually distracted and uncomfortable. In the event, however, their guests rise to the occasion...leaving Nigel even more bereft than when he started. Meanwhile, Alan, a scion of the middle class employed at the same firm, is a veritable Mr. Memory when it comes to the aristocracy: he's made a detailed study of the lineage, likes and loves of the rich and famous. With his wife April and their dozen cats, Alan has made a lifework out of anomie. Who's Who, among other things, sends up British television as Americans know and love it: these upper-class twits who are old before their time hold little glamor, while Alan's fixation with his betters registers beyond the pale. Leigh always makes us laugh, but he's not happy until he makes us squirm.
