Mike Jackson, cricketer and scion of a cricketing clan, finds his dreams of studying and playing at Cambridge upset by news of his father's financial troubles, and must instead take a job with the "New Asiatic Bank". On arrival there, Mike finds his friend Psmith is also a new employee, and together they strive to make the best of their position, and perhaps squeeze in a little cricket from time to time.Playing cricket for a team run by Psmith's father, Mike meets John Bickersdyke for the first time when he walks behind the bowler's arm, causing Mike to get out on ninety-eight. Shortly afterward, Mike's father regretfully informs him that, having lost a large amount of money, he will have to sell the house, and won't be able to send Mike to Cambridge as he had hoped. Mike hears that Psmith is in the same position, as he is sent off to London.
Mike, feeling very lonely, homesick and sorry for himself, rents a horrid room in Dulwich, and next day presents himself for work at the New Asiatic Bank. He is put to work under Mr Rossiter in the Postage Department, replacing a youth named Bannister, and is befriended by Mr Waller, a kindly employee of the bank, who takes him to lunch; on his return, he is joined by Psmith, also a new employee, in the same department as Mike.
They go for a stroll, and Psmith reveals that he has been placed there on a whim of his father's, having annoyed Bickersdyke while he was staying for the weekend. Mike is worried that their employer has it in for them both and that they are powerless, but Psmith announces he plans to toy with Bickersdyke outside of work, being, like their employer, a member of the Senior Conservative Club. He also insists that Mike move in with him in his flat in Clement's Inn. That night Mike feels much happier for having an ally.
Trying to find a means of pacifying their manager Mr Rossiter, they find out from Bannister that he is a devotee of association football and a fan of Manchester United. For a few weeks Psmith uses this knowledge to ingratiate himself with Rossiter, before moving on to Bickersdyke. He haunts the man at their club, his position in the workplace unassailable thanks to his friendship with Rossiter, and disrupts a political meeting, part of Bickersdyke's campaign to become a member of parliament, turning it into a near-riot. Bickersdyke is angry at Psmith, but powerless.
Psmith continues to cultivate Mr Rossiter, and Mike gets used to his work. After a while, a new man starts, and Mike is moved on to the Cash Department, under Mr Waller. One day, hearing Psmith call Mike "Comrade", Waller reveals that he is an ardent socialist, and Psmith agrees to come and hear him speak, dragging Mike along. When a spectator goes to throw a stone at Waller, Mike intervenes, and a fight starts, which soon involves Psmith and a mob; the friends flee. Returning that evening for tea, Mike has an awful time, but Psmith acquires Waller's book of the proceedings of the "Tulse Hill Parliament", including some particularly fiery words from Mr Bickersdyke.
One day, worried by his son being ill, Waller fails to spot a forged cheque. To save the man's job, Mike takes the blame, and is fired and roasted by Bickersdyke. After work, Psmith trails Bickersdyke to a Turkish bath and threatens to leak Bickersdyke's anti-royalty speeches from the Tulse Hill book. Bickersdyke, furious, agrees to keep Mike on at the bank. Soon after, he is narrowly elected to Parliament, rendering the threat of the book useless, and Mike is moved to a new department, Fixed Deposits, a much less pleasant spot, with Psmith replacing him under Mr Waller.
As spring and sunshine arrive, Mike begins to long for the outdoors and his beloved cricket. One day, he is called by his brother Joe, who is playing for their county at Lord's. They are a man short, and need Mike to play; he agrees, asking Psmith to tell his new boss he has to "pop off"; the boss tells Mr Bickersdyke, who, as usual, is furious. Mike, convinced his job is over, resolves to play his heart out.
Psmith leaves work early, to take his father to the match. Mr Smith is shocked that the bank does not approve of people leaving to play cricket; Psmith persuades him that rather than working at the bank, he should study for the Bar. They arrive at the game just as Mike, playing well, reaches his century. After the match, Psmith tells Mike of his plans to study Law at Cambridge, and also that his father, needing an agent for his estate, is willing to take Mike on, having first paid for him to go to the 'varsity too, to study the business.
Mr Bickersdyke, relaxing in his club, overjoyed at the thought of finally being able to sack Psmith and Mike, is further enraged when Psmith sympathetically announces their retirement from business.
