Star Trek: Discovery S02E01: New Eden by an author from IMDb
A new signal brings the Discovery to a distant planet, Terralysium, that is inhabited by the descendants of human survivors of World War III, which was fought on Earth 200 years earlier and prompting Stamets' emotional return to the mycelial network and leading Burnham, Pike and Owosekun to a pre-warp planet, where they face a complex ethical dilemma. Tilly's overeagerness lands her in trouble but when the planet - and Discovery's landing party - are threatened, her curiosity may be the one thing that can save them.
