An apartment on the Tiber riverfront, in the center of Rome. The director lives here, where Stella lived until her death. Stella is the nom de guerre of Alba Meloni, a partisan courier who, at a very young age, joined the Resistance in the capital. After Liberation, she became an official of the Italian Communist Party and spent the last 30 years of her life in the Testaccio neighborhood, where she is still a very popular figure. The director follows in her footsteps, talking to her, collecting her memories, capturing fragments of her daily life and experiences: at home, in the neighborhood, and on the streets of Rome, where the girl once carried weapons in a straw bag and planted nails on the roads to stop German trucks. It is a journey through time and the city, during which Alba/Stella's individual story intertwines with our collective history.
