The short version
Ye Wenjie's experience of political violence leaves her disillusioned with humanity before her work at the secret Red Coast base brings contact with an alien civilization. She answers despite a warning that further communication will expose Earth to invasion. Decades later, scientist Wang Miao investigates disturbing failures of scientific experiments and enters the Three Body game. It introduces a civilization struggling with an unstable three-star system and leads him toward a human organization assisting the aliens. Wang's inquiry connects the earlier invitation to a threat that has already begun interfering with Earth's scientific development.
