The Omega Man

In a post-apocalyptic Los Angeles, Dr. Robert Neville (Charlton Heston) is the sole human survivor of a biologically waged war, struggling to maintain his sanity as he patrols the desolate city and hunts down "the Family," a cult of plague victims who have become homicidal nocturnal albino mutants. He discovers a vaccine that renders him immune but realizes it won't save humanity unless he can duplicate it, leading him to create a serum from his own blood. As Neville navigates his new reality, he must confront the moral implications of his discovery and face off against the Family's ruthless leader, Jonathan Matthias (Anthony Zerbe), who seeks to destroy all remnants of technology.
