Dublin; June 16, 1904. Stephen Dedalus, who fancies himself as a poet, embarks on a day of wandering about the city during which he finds friendship and a father figure in Leopold Bloom, a middle-aged Jew. Meanwhile, Bloom's day, illuminated by a funeral and an evening of drinking and revelry that stirs paternal feelings toward Stephen, ends with a rapprochement with Molly, his earthy wife.

Over lunch at the Four Seasons Hotel, an acquaintance tells the protagonist about his troubles.
