A virus called the "Grey Death" sweeps the world, turning those infected into bloodthirsty monsters. As a biological researcher, Cheng Mo escaped from the laboratory with key data before it fell and became one of the few survivors.
Three months after the virus broke out, Cheng Mo survived alone in an abandoned city, relying on caution and scientific knowledge to avoid infected people while searching for other survivors and possible clues to an antidote.
-Cheng Mo rescued Ning Yuwei, a seemingly weak young woman who was besieged by the infected while searching for supplies. After a brief conflict, the two decided to go together.
Ning Yuwei showed unusual calmness and fighting ability, suggesting that she was no ordinary survivor, while Cheng Mo also concealed the secret that the laboratory data he carried might contain the origin of the virus.
The two went to a military base on the outskirts of the city to find shelter. On the way, Ning Yuwei showed an unusual understanding of infected people, while Cheng Mo discovered suspicious scars on her arms.
When Cheng Mo's backpack was accidentally opened, revealing laboratory documents, Ning Yuwei's eyes became sharp, implying that the two of them had ulterior motives and that their encounter might not have been accidental.
