Psmith, a resourceful gentleman, falls for Eve Halliday while offering her his (borrowed) umbrella. To be near her, he impersonates a poet at Blandings Castle, Eve's new workplace. Meanwhile, chaos unfolds. A necklace goes missing, a runaway daughter returns, and Lord Emsworth (the hapless owner of the castle) desperately needs funds. Through a series of hilarious mishaps, mistaken identities, and witty exchanges, Psmith untangles the mess, recovers the stolen gem, and wins the heart of his dream girl.
