The only girl in the world is a French-language romance drama centered on Carole, a young woman who feels more at home in fantasy than in ordinary life. Her imagined self is confident, outgoing and passionate—the opposite of how she sees herself.

When Suzanne becomes Carole’s new best friend, admiration gradually turns into love. Suzanne represents the qualities Carole has long wanted for herself, prompting her to consider how far she can bring her private fantasy into the real world.

The only girl in the world movie details

Story without spoilers

Carole is melancholic and withdrawn, but she has created an inner world in which she can become someone very different: extroverted, passionate and unconstrained. This imagined identity gives her a way to explore feelings that remain difficult to express in her everyday life.

Her perspective shifts after she meets Suzanne, her new best friend. Carole falls in love with her, while also recognizing in Suzanne the traits she has always desired. Rather than simply remaining inside her fantasies, Carole decides to give them a place in her lived experience. The film’s premise follows that decision without revealing how it develops or where it leads.

What to expect

With a 15-minute runtime, The only girl in the world presents a compact character-focused story rather than an expansive romance. Its drama grows from Carole’s melancholy, her imaginative inner life and her feelings for Suzanne. The premise also introduces a clear contrast between the person Carole believes she is and the person she imagines becoming.

The romance is framed through friendship, admiration and self-projection. Because the film is presented as a drama as well as a romance, viewers can expect the emotional conflict to be tied closely to Carole’s identity and her attempt to connect fantasy with reality. The supplied details do not establish a specific visual style, ending or broader thematic resolution.

Cast and creative team

Lucien Mille-Levy directs and writes The only girl in the world. Carole Mounier plays Carole, while Suzanne Mille-Levy plays Suzanne. The story’s focus rests on the connection between these two characters and on Carole’s changing understanding of herself through that relationship.
