I Am Legend

In 2009, a genetically engineered measles virus designed to cure cancer mutated and killed 90% of the human population, and transformed another 9% into vampiric-zombies known as Darkseekers, who hunt for immune humans at night as they are vulnerable to sunlight. In 2012, three years after the outbreak, U.S. Army virologist LTC Robert Neville and his German Shepherd, Sam, live in a heavily fortified Washington Square Park home in deserted Manhattan. Neville's daily routine includes experimenting on rats to find a cure for the virus, searching the city for supplies, and waiting each day for survivors to respond to his recorded radio broadcasts to meet him at the South Street Seaport by noon. At night, he barricades himself with Sam inside his home. Neville is haunted by memories of his wife Zoe and daughter Marley, who died in a helicopter accident during the chaotic evacuation. While Neville hunts a deer, Sam pursues it into a building populated with Darkseekers. Neville and Sam narrowly escape. Neville sets a trap with his immune blood and captures a female Darkseeker to use as a subject for his treatment. An alpha Darkseeker pursues them but is halted by sunlight. Neville's treatment of the Darkseeker seems unsuccessful. Neville notices a mannequin placed outside Grand Central Terminal. As he approaches it, he is caught in a trap and loses consciousness. He awakes at dusk and the Alpha unleashes infected dogs. Neville frees himself and subdues the dogs, but Sam is bitten. Back in his lab, Neville injects her with his serum to no avail. Sam begins to transform and Neville strangles her. Neville assaults the Darkseekers with his car, but is vastly outnumbered. He is rescued by immune survivors Anna and Ethan, who heard his broadcast. They take Neville home, where Anna explains they survived on a Red Cross ship from São Paulo, and are heading to a survivors camp in Bethel, Vermont. Neville says no such camp exists. Working to cure the female Darkseeker, Neville suggests cooling her with ice to improve treatment. Darkseekers launch an invasion on the house. Neville, Anna, and Ethan seal themselves in the basement laboratory with the test subject where Neville discovers the female Darkseeker is slowly turning back to human. The Alpha Darkseeker begins breaking through the glass door. Neville draws a vial of blood from the cured Darkseeker and gives it to Anna before shutting her and Ethan inside a coal chute in the back of the lab. Neville then sacrifices himself, killing the attacking Darkseekers with a grenade. Neville realizes that the Alpha is identifying the woman he was experimenting on by a butterfly tattoo, and that it wants her back. Neville puts his gun down and returns the infected woman. He and the Alpha then exchange stares; Neville apologizes to them, which the Alpha acknowledges before the infected leave. Neville, Anna, and Ethan drive away towards Vermont.
