At the beginning of the 21st century, the basic science of the earth was shaken like never before. Many scientists became desperate and crazy and committed suicide.On the eve of the approaching storm, many sensitive people faintly smell the breath of destruction.

On this day, nanoscientist Wang Miao (played by Zhang Luyi) was invited to the Joint Operations Center by the rude police officer Shi Qiang (played by Yu Hewei), and then learned that the deaths of the scientists seemed to be related to an organization called “Science Frontier (ETO)”.The operations center hopes that Wang Miao will infiltrate the organization and investigate their relationship with death scientists and even a mysterious game-Three-Body.

Wang Miao and Da Shi are deeply confused and curious by the constant countdown numbers in front of them, the flickering of the universe predicted by ETO leader Shen Yufei (played by Li Xiaoran), and the continuous destruction and rebirth of civilizations in Three-Body.As for the seemingly ordinary elderly scientist Ye Wenjie (played by Chen Jin), her appearance leads everything to the unknown a few light years away...

The film is adapted from Liu Cixin's science fiction novel of the same name.
