Charles paints his bath with red enamel, and is delighted to receive an invitation to a prestigious event held by London's Lord Mayor at the Mansion House.

Further social humiliation for poor old Pooter and his wife Carrie when their names are omitted from the Mansion House Ball's attendance list by the local newspaper. Not to mention the return of their son Willie, now calling himself Lupin and insisting on some rather unseemly behaviour.

In the rollercoaster lead up to Christmas, Pooter suffers embarrassment in the card shop, receives an insulting Christmas card and a punch in the head at a rather raucous evening with the Holloway Comedians. Lupin falls in and out of love with Daisy Mutler, and both father and son receive some very good news.

Pooter is a proud man when Lupin gains a position at the firm Perkupp and Co. But after he he loses them their most valued client and is sacked, he becomes engaged to an unsuitable young lady. However, Pooter acknowledges that the young must make their own way in life. He is then struck by the most wonderful good fortune and is rewarded beyond his wildest dreams.
