When the dapper and eccentric Psmith is forced into the mundane world of banking, he initiates a campaign of sophisticated disruption against his pompous manager, Mr. Bickersdyke. Psmith, a young man of leisure and sharp wit, finds his new employment at a City bank entirely incompatible with his refined sensibilities. He navigates the rigid hierarchy of the financial institution with a mix of nonchalance and calculated mischief, aiming to unsettle his superior at every turn. The narrative follows a linear progression, utilizing a third-person perspective to highlight the absurdity of the corporate environment through Psmith's unique, articulate observations.

Readers frequently highlight the linguistic dexterity and rhythmic prose that define Wodehouse's comedic style. Discussion often centers on the effectiveness of Psmith as a protagonist who remains unflappable regardless of the social or professional pressure applied to him. Critics note that the book serves as a sharp, yet gentle, satire of the rigid social structures prevalent in early 20th-century London. The balance between the protagonist's witty observations and the escalating office conflicts provides a consistent pace that keeps the narrative engaging. Many readers appreciate the way the author uses the mundane setting of a bank to showcase the absurdity of human vanity.
