3 Body Problem plot

Netflix has produced a handy summary of the 3 Body Problem plot, one which still preserves the mystery of what's to come. 

"The story begins in 1960s China, when a young woman makes a fateful decision that reverberates across space and time into the present day. When the laws of nature inexplicably unravel, a tight-knit group of brilliant scientists must join forces with an unflinching detective to stop humanity's greatest threat. 3 Body Problem is an epic story that redefines sci-fi drama with its layered mysteries and story of human connection". 

You might notice that the show has made some creative changes to the original story, including switching up characters and some locations from the books. Those changes include making some changes to the timeline of the story, some additions, and switching the story primarily over to being based in the UK. However, a Tudum article explains that the three creators got Cixin Liu's blessing when it came to adapting his work.

Benioff said: "We have a tremendous love and respect for the books. You can't devote every waking moment of your life for years on end to adapt a piece of work that you don't love. 

"So it's very important to us that the show stand on its own two legs and work for people who have read the books — and for people who haven’t read the books.”
