“3 Body Problem” Summary

Netflix’s “3 Body Problem” is a sprawling, ambitious sci-fi thriller based on the Chinese novel “The Three-Body Problem” by Cixin Liu. Created by Alexander Woo and “Game of Thrones” showrunners David Benioff and D.B. Weiss, this Netflix series puts a group of scientists on the cusp of dangerous discoveries about the world. Inspired by actual history and physics, “3 Body Problem” bends space and time to tell a story questioning who else is out there in the universe and what they want.

“3 Body Problem” starts during the Cultural Revolution in 1960s China; a young astrophysicist named Ye Wenjie (Zine Tseng) sees her father executed.  The story then takes us to present-day London, where Clarence Shi (Benedict Wong) is investigating a string of mysterious suicides linked together by all the deaths being scientists. One of these deceased scientists brings together a group of her ex-students in mourning; these students are the Oxford Five. Saul (Jovan Adepo), Auggie (Eiza Gonzalez), Jin (Jess Hong), Will (Alex Sharp), and Jack (John Bradley) all reunite in shock over the death. But these scientists are about to individually encounter their own struggles with unexplained phenomena. 

Mysterious countdowns, cults, video games, and murder are all connected to an alien species that’s coming to earth. While their intentions remain ambiguous and foreboding, what we do know is that Ye Wenjie’s actions in 1960s China led to this invasion of the world.
