In the breathtaking landscapes of Iceland, a quiet choir conductor named Halla Halldora Geirharosdottir leads a dangerous double life as a passionate environmental activist. Declaring a one-woman war on the local aluminum industry to protect the pristine highlands, she executes daring acts of sabotage that capture the nation's attention and baffle the authorities. As her covert campaign escalates, a long-dormant application to adopt a child is suddenly approved, presenting Halla with an impossible conflict between her fierce maternal hopes and her unwavering commitment to the planet. Directed by Benedikt Erlingsson, this genre-blending drama-thriller masterfully weaves deadpan humor with high-stakes tension, following a modern-day folk hero who must navigate the complexities of personal desire and global responsibility. With a mysterious twin sister, a bumbling tourist Juan Camillo Roman Estrada, and a government minister Johann Siguroarson on her trail, Halla's journey becomes a uniquely compelling and surprisingly melodic battle for the future.
