Ulysses follows three Dubliners through a single day, 16 June 1904. Stephen Dedalus is a young teacher and would-be writer, proud, grieving his mother, and at odds with the friends he lodges with. Leopold Bloom is a Jewish advertising canvasser, kind and curious, quietly aware that his wife plans to meet another man that afternoon. Molly Bloom is his wife, a singer, whose long night thoughts close the book.
The opening movement stays with Stephen: shaving on a tower with the mocking Buck Mulligan, teaching a history lesson, then walking the strand alone, where his mind turns over memory, language, and the line that history is a nightmare from which he is trying to wake. His sections are dense with reference and self-conscious thought.
The day then shifts to Bloom and rarely leaves him for long. He makes breakfast, attends a funeral, drifts through his work, eats lunch, and moves among the shops, pubs, and streets of the city. His interior monologue is the book's warm center: practical, sensual, distractible, returning again and again to his dead infant son Rudy and to his marriage.
As the day runs on, the writing grows more experimental. One episode is told in newspaper headlines, another swells into mock-heroic tirade, another parodies the whole history of English prose, and a long night chapter dissolves into hallucination. Bloom and Stephen finally cross paths and, after the night's wandering, Bloom brings the younger man home, a quiet meeting of the two men the book has been steering toward.
The book ends inside Molly's mind. In eight unpunctuated streams of thought she runs over her lovers, her girlhood in Gibraltar, her husband, and her own appetites, drifting toward sleep. Her closing assent, ending on the word yes, returns the whole vast day to a single human bed and a single human voice.
