The film traces Sirima's path to her tragic fate. Sirima, a 24-year-old French-Sri Lankan singer, was stabbed to death by her partner on the night of 6–7 December 1989, just weeks after the release of her debut album, A Part of Me.
Sirima's voice left a lasting impression on the passengers of the Chatelet-Les Halles metro station who heard her singing while she was busking there. The metro was her first stage and her first audience. Her voice and her personality inspired a professional musician, saxophonist Philippe Delettrez, whom she came to trust. Together, they composed, wrote and recorded an album at Davout Studio with great musicians and a symphony orchestra. Everything happened very quickly.
