Alfie Byrne is a middle-aged bus conductor in Dublin in 1963. He would appear to live a life of quiet desperation: he's gay, but firmly closeted, and his sister is always trying to find him "the right girl". His passion is Oscar Wilde, his hobby is putting on amateur theatre productions in the local church hall. We follow him as he struggles with temptation, friendship, disapproval, and the conservative yet oddly lyrical world of Ireland in the early 1960s.

Jimmy Rabbitte, just a tick out of school, gets a brilliant idea: to put a soul band together in Barrytown, his slum home in north Dublin. First he needs musicians and singers: things slowly start to click when he finds three fine-voiced females virtually in his back yard, a lead singer (Deco) at a wedding, and, responding to his ad, an aging trumpet player, Joey "The Lips" Fagan.
