Set after the collapse of the Earth’s ecosystem, the film follows Vesper (Chapman), a headstrong 13-year-old girl who uses her survival skills to subsist in the remnants of a strange and dangerous world with her ailing father, Darius (Brake). When Vesper finds a mysterious woman, Camellia (McEwen), alone and disoriented after an aerial crash, she agrees to help her find her missing companion in exchange for safe passage to the Citadel – the dark central hub where oligarchs live in comfort thanks to state-of-the-art biotechnology. Vesper soon discovers that her brutal neighbor, Jonas (Marsan), is searching for Camellia, who is harboring a secret which could change all of their lives forever. Forced into a dangerous adventure, Vesper must rely on her wits and bio-hacking abilities to unlock the key to an alternate future.
