And Earth becomes their target. We follow Ye Wenjie, a disillusioned astrophysicist whose experiences during the Cultural Revolution shape her critical role in the events that unfold. We also meet Wang Miao, a nanotechnology researcher who enters the mysterious virtual world of "Three Body” a simulation that allows players to experience the Trisolaris system and their constant struggle to survive within its unpredictable physics.
