Sixteen years ago, a buried past event changed the lives of Ye Minggao and Lin Wenye.
Sixteen years later, Chen Bosheng, an executive of Wensheng Group, passed away unexpectedly. An unsent email about an "old accident" resurfaced the long-sealed past. Ye Minggao returned to Wen Sheng as a crisis management consultant, and Lin Wenye also began to discover from the fragmented memories that his forgotten past might be closely connected with her.
An old photo, a recording, a seven-minute agreement, and contradictory clues that continue to appear push the two closer to the truth step by step. They test and cooperate with each other, and always keep their own secrets. The closer we get to the past, the harder it is to tell who is taking advantage of whom, and who can really be trusted.
"Hypoxia" takes suspense investigation and character relationships as the main line, telling the story of two people implicated in old secrets, searching for the truth among lies, interests and memories, and learning to make choices for themselves again.
