In order to escape the wrath of Honoria Glossop and Aunt Agatha, Jeeves and Bertie board an oceanliner heading for New York. Unfortunately, Bertie is landed with the task of looking after Wilmot Malvern, a lad long cooped up with his mother Lady Malvern. He turns out to be a limpet of the worst sort with the knack for clinging to Woosters. On the ship Bertie also runs into Tuppy, who's off to America to become an importer of cars to Britain. Once in New York, the mother's boy breaks loose onto the nightclub scene with disasterous results, and Tuppy meets with similar lack of success when he realizes he'll have to buy more than one car at a time and that the steering wheel's on the wrong side.

The aunt of Bertie's poet friend, Rocky, wants him to go out and live the New York nightlife and write her weekly letters so that she might experience it vicariously. Rocky, however can't stand anything but his cabin the the wilderness of Long Island, so Jeeves agrees to undergo the rigors and report back to Rocky. Another friend, Bicky, loves New York, but his uncle thinks he should be in Colorado. Jeeves suggests a bit of deception on his part as well, which works fine until relatives of both friends show up in New York, both believing that Bertie's flat belongs to their respective nephews. Solutions involve a lot of running about acting silly and quite a bit of handshaking as well.

Cyril Bassington-Bassington arrives in New York under specific instructions from Aunt Agatha for Bertie to keep him out of theatrical circles - instructions which of course Cyril rips up before Bertie can read them. So he lands a part in a Broadway musical called Ask Dad! and Bertie tours the USA with the show.

Meanwhile, Bertie's struggling artist friend, Corky, needs help convincing his uncle that the girl he wants to marry is suitable. Unfortunately Jeeves' solution may be too good.

After a wild night with Catsmeat Potter-Pirbright, Gussie ends up in stir for wading about Trafalgar fountain looking for Newts. For purely simple and logical reasons Bertie goes to Devirill Hall pretending to be Gussie in order to win the aunts' approval of his marriage to Madeline Basset, and Gussie must go under the name Bertie Wooster to woo Catsmeat's fiancé, Gertrude Winkworth.

Sir Watkin Bassett is writing his memories, which could prove scandalous to everyone in his life, so various members of society, such as Madeline Bassett, and Lady Florence Cray -- to whom Bertie has recently become engaged -- all want Bertie to steal them.

Stiffy Byng is producing the village entertainment for Totleigh-on-the-Wold involving Mike & Pat Cross talk between Gussie and Spode, and a song by her betrothed, Stinker Pinker.
