Agnese is a girl living a quiet life, passionate about competitive diving, until a double blow turns everything upside down: her family's financial collapse and the abandonment of her father Mario. Forced to leave her world behind, she finds herself living in the Grattacielo di Rimini, in the heart of Marina Centro. What seems like a last resort turns out to be a surprising place: the building is a lively microcosm, populated by eccentric figures such as Altiero, an improvised caretaker with a biker past, and Perla, a mysterious former showbiz star who passes herself off as a beautician. The real turning point comes with Melo, a neurodivergent young man who, together with his friends Gas and Giac, tends an urban garden on the very rooftop of the building. Through these unexpected encounters, Agnese discovers that even on the margins of her own life, something precious can be found.
