Jack, the protagonist, travels alone through a city in ruins. Ahead lie an abandoned supermarket and collapsed buildings. There, Jack faces the infected, who are no longer “Shadow People.” He discovers that they are beginning to display “human-like” traits again, yet they remain clearly different from ordinary people: they are stronger, more violent, and seem to possess a degree of organization.
Jack finds a discarded notebook containing Neville’s unpublished research data and a new discovery: this latest evolutionary variant does not kill its Host outright. Instead, it transforms the Host into a “super-infected” person, exceptionally powerful but stripped of all human emotion and reason.
While out searching for food, Jack encounters a small group of survivors. They seem normal, but something strangely unfamiliar comes through in the way they speak and behave.
As Jack and the survivors fight one battle after another, they gradually uncover the secrets behind the new virus. They discover that the virus is not evolving aimlessly; it seems to be controlled by some kind of intelligence. Behind this “intelligence” may lie a form of genetic memory within the virus, or perhaps a more complex “symbiotic” system.
In the final confrontation, Jack discovers that Neville’s sacrifice was not in vain. Jack must make a choice: continue searching for the ultimate cure for the virus, or try to coexist with it and find a new way to survive?
The story is pretty good, a bit mediocre, worth watching.
