In Greta Thunberg’s wake, the young have commenced an unrelenting struggle to save our planet. At the front of these corteges, and making headlines in the media as well as on social networks, young women have become the movement’s figureheads, sometimes in spite of themselves. The film follows young activists around the globe Anuna and Adélaïde (Belgium), Luisa (Germany), Léna (France), Leah (Uganda), and Mitzi (Philippines). A picture emerges of a course shared by “sisters in arms” who are driven by hope, commitment, and exceptional ideals.
