Lia lives on her parents’ farm, a place where she is happy and where every night is spent staring at the immense starry sky, a magical moment for her. When her family announces that they will visit her aunts, Lia is thrilled with the prospect of getting to know the city for the first time. What she didn’t imagine is that the city is a place where everyone goes in a hurry, the noise is constant and at night it is impossible to see a single star.

Together with her cousin Pau, Lia begins a particular crusade to achieve a sustainable, clean and environmentally friendly city.
