In this mind-bending sci-fi epic, a series of mysterious deaths among scientists around the globe triggers a desperate investigation by a group of brilliant but fractured researchers. When astrophysicist Jin Cheng (played by Jess Hong) and her former mentor, the unconventional genius Will Downing (portrayed by Alex Sharp), uncover a cryptic connection between the deaths and a secretive online game, they are drawn into a conspiracy that spans decades and challenges the very laws of physics. The story weaves between 1960s China, where a young physicist named Ye Wenjie (depicted by Rosalind Chao) makes a devastating choice during the Cultural Revolution, and the present day, where her actions ripple outward to threaten all of humanity. As the team races to decode the game's clues, they confront an unimaginable alien threat from a dying star system, forcing them to question whether human nature itself is their greatest weakness. Balancing hard science with philosophical dread, the series creates an atmosphere of escalating paranoia and cosmic horror, exploring themes of trust, betrayal, and the fragility of civilization.
