I Am Legend (film)

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, when Neville stayed behind on the island as military personnel. Neville's only mitigation for his loneliness is his German Shepherd named Samantha, a.k.a. Sam (given to him by his daughter as a puppy to protect him before she died in the helicopter crash), interaction with mannequins he has set up as patrons at a video store, and recordings of old television broadcasts. At night, he barricades himself and Sam inside his heavily fortified Washington Square Park home to hide from the Darkseekers. One day, while waiting for survivors, Sam follows a deer into a dark building. Neville cautiously goes in after her and finds the deer's corpse along with Sam, but the building is infested by a colony of Darkseekers. Both manage to escape unharmed and the attacking Darkseekers are killed by the sunlight.
