About the series
During the "Cultural Revolution," China sends a signal into space, hoping to get a response from an extraterrestrial civilization. It arrives at the start of the 21st century: unknown forces try to slow down humanity's scientific progress. The large-scale sci-fi series, spanning several timelines, was created by "Game of Thrones" showrunners David Benioff and D. B. Weiss. Its plot is based on the popular novels of Chinese science-fiction writer Liu Cixin.
