what happened at the end of i am legend
I Am Legend (film) Neville once again attempts to administer a potential cure to the infected woman in his laboratory, but the next night, a group of Darkseekers, who had followed Anna and Neville back the night before, attacks the house. Neville, Anna, and Ethan retreat into the basement laboratory, sealing themselves in with the female Darkseeker on which Neville has been experimenting. Discovering that the last treatment was successful, Neville tries to assess the situation as the alpha male deliberately rams himself against a glass door to break in. Neville draws a vial of blood from the woman he cured and gives it to Anna, before shutting her and Ethan inside a coal chute in the back of the lab. He then takes a grenade and kills the Darkseekers at the cost of his own life, saving the cure. The next day, before dusk, Anna and Ethan discover that her theory is right as they arrive at the survivors camp in Vermont. They are greeted by military officers and other human survivors before Anna is shown handing the cure to military personnel.
