In 2009, a genetically re-engineered measles virus, originally created as a cure for cancer, turns into a lethal strain which kills 94% of those it infects, mutates 5% into predatory, nocturnal mutants called "Darkseekers" who are extremely vulnerable to sunlight and other sources of UV, with only the remaining 1% immune.

Flashbacks reveal that his wife (Salli Richardson) and daughter (Willow Smith) died in a helicopter accident during the chaotic evacuation of Manhattan, prior to the military-enforced quarantine of the island in 2009, in which Neville stays behind on the island as military personnel.

At night, he barricades himself and Sam inside his heavily fortified Washington Square Park home to hide from the Darkseekers.
