Once

An unnamed, thirtysomething Dublin busker (listed in the credits as “Guy” and played by Glen Hansard) sings and plays guitar on Grafton Street, a Dublin shopping district, struggling with the trials of performing on the street, including chasing after a heroin addict (Darren Healy) who attempts to steal his earnings. Lured by his music, an unnamed young Czech immigrant flower seller (listed in the credits as “Girl”, played by Markéta Irglová) approaches him impertinently during one of his late night street performances and, despite his annoyance, persists in questioning him about his songs. Upon learning that he also repairs vacuum cleaners in his father’s shop, she insists that he fix her broken vacuum.
The next day she brings her Hoover by and parlays it into lunch together, whereupon she piques his interest by telling him that she’s a musician too. He asks to hear her play, so they visit a music store where she regularly plays piano. After teaching her one of his songs (“Falling Slowly”), which she picks up easily, they sing and play the song together, kindling a musical and potentially romantic connection. He invites her and her ailing vacuum back to his father’s shop, and on the bus home musically answers her question as to what his songs are about: a long-time girlfriend who cheated on him, then left (“Broken Hearted Hoover Fixer Sucker Guy”). At the shop, he repairs her vacuum and she meets his father (Bill Hodnett), who seems indifferent to his son’s musical talent. The Guy takes the Girl up to his room, but when he asks her to stay the night, she is insulted and leaves. The next day, he apologizes and they quickly patch things up, as over the course of a week they excitedly write, rehearse and record songs, and get to know each other. Songs continue to be performed in a real-world, diagetic fashion, often in their entirety, as when the Girl rehearses her lyrics for one of the Guy’s songs (which she entitles “If You Want Me”), singing to herself while walking down the street, or when at a party, people perform impromptu (including “Gold”, performed by a trio featuring guitarist Hansard singing harmony).
Their flirtation continues, but at the same time, he is thinking about and writing about (“Lies”) his ex-girlfriend (Marcella Plunkett), who moved to London. The Girl encourages him to move there, win his girlfriend back and pursue his musical career. Invited home to dinner by the Girl, the Guy discovers that she has a baby (Kate Haugh) and lives with her mother (Danuse Ktrestova). He soon decides that it is time to move to London, but he wants to make a high-quality demo of his songs to take with him and asks the Girl to record it with him. She takes the lead as they secure a bank loan—from a bank where the loan officer (Sean Miller) is a musical hobbyist—and reserve time at a professional studio. On a romantic motorbike jaunt, she reveals, much to his consternation, that she’s married, though her estranged husband is back in the Czech Republic. When Guy asks if she still loves her husband, she answers in Czech and coyly declines to translate what she said. After recruiting a trio of musicians (Gerard Hendrick, Alaistair Foley, Hugh Walsh), they rehearse, then go into the studio to record. Their lack of experience shows, but they quickly impress the jaded studio engineer Eamon (Geoff Minogue) once they begin recording their first song (“When Your Mind’s Made Up”). On a break in the wee hours of the morning, the Girl finds a piano in an empty studio and finally plays the Guy one of her own compositions (“The Hill”), though she breaks down before finishing the song, which tells of romantic frustration. He responds by asking her to come with him to London, but isn’t prepared for the reality of her mother coming along to help with the baby.
Still, he is smitten. After the session wraps up successfully, he asks her to spend his last night in Dublin with him; she says that it would only result in “hanky-panky,” which is a “bad idea”, yet she ultimately agrees to come over. But in the end, she stands him up and he can’t find her to say goodbye before his flight. He plays the demo for his father, who, moved and impressed, gives him money to help him get settled in London. Before leaving for the airport, the Guy buys the Girl a piano and makes arrangements for its delivery, then calls his ex-girlfriend, who is happy about his imminent arrival. The Girl’s husband (Senan Haugh) moves to Dublin and they reunite. But the final shots convey how the Girl and the Guy were deeply affected by their short time together.
