In a society where life expectancy keeps expanding and human fragility becomes ever more tangible, characters like Chris, Sabina, and the residents of Sun City West move between fear and hope. Chris, a biologist from London, studies naked mole rats in an attempt to extend human life, yet remains skeptical of science’s grand ambitions.
Sabina, an elderly Italian resident, dreams of using the Sarco — the assisted-suicide device designed by Philip Nitschke — but must face obstacles, prejudice, and her own inner doubts. In the Arizona desert, Sun City West emerges as a social experiment in eternal happiness and longevity: a city built to defeat aging, where the promise of endless life coexists with the fear of its own limits.
