The world has fallen. The infected remain conscious, but their bodies are controlled by fungal threads. They crawl toward high places, then burst open and scatter spores.
In the end, they become conscious, wandering zombies.
Medical student Gu Yan wasn't wearing a mask. Blood splashed into his right eye, yet he survived.
He didn't turn into a monster. Instead, he became the only half-infected person: able to pass as a zombie and blend into the horde, sense the location of every infected person, and even control them.
But the military of Country M has identified him as "Sample No. 100."
When H-48 evolves, he too will lose his human consciousness completely.
Before he becomes a monster, he must survive and find a cure.
--And it all began on Flight MU173.
