Ulysses follows one day in Dublin in 1904--tracing the paths of two characters: a middle-aged Jewish man by the name of Leopold Bloom and a young intellectual, Stephen Daedalus. Bloom goes through his day with the full awareness that his wife, Molly, is probably receiving her lover at their home (as part of an ongoing affair). He buys some liver, attends a funeral and, watches a young girl on a beach.
Daedalus passes from a newspaper office, expounds a theory of Shakespeare's Hamlet in a public library and visits a maternity ward--where his journey becomes intertwined with Bloom's, as he invites Bloom to go along with some of his companions on a drunken spree. They end up at a notorious brothel, where Daedalus suddenly becomes angry because he believes the ghost of his mother is visiting him.
He uses his cane to knock out a light and gets into a fight--only to be knocked out himself. Bloom revives him and takes him back to his house, where they sit and talk, drinking coffee into the wee hours. In the final chapter, Bloom slips back into bed with his wife, Molly. We get a final monologue from her point of view. The string of words is famous, as it is entirely devoid of any punctuation. The words just flow as one long, full thought.
