Silo has been the latest obsession for sci-fi fans, standing tall as one of Apple TV+’s flagship series. The science-fiction adaptation of Hugh Howey’s “Wool” series follows a community of survivors relegated to life underground after a post-apocalyptic event. When mechanical engineer-turned-sheriff Juliette Nichols (Rebecca Ferguson) unearths secrets about the origins and maintenance of the silo, she triggers a series of reactions that transforms life as everyone understands it in the silo.
