Robert Morgan is a scientist who lives in a world where humanity has been wiped out by a mysterious plague. He spends his days scavenging for food and supplies, and his nights barricaded inside his home as a swarm of vampires, who were once human, attempt to break in and kill him.
Morgan is the last known survivor of the plague, and he spends much of his time trying to find a cure for the disease. He experiments with the blood of the vampires, trying to understand the nature of the virus that caused the plague. He also tries to communicate with the vampires, hoping that they might have some insight into the disease.
Despite his efforts, Morgan's life is a solitary and depressing one. He is haunted by memories of his family, who died in the early days of the plague, and he struggles with the guilt of being the only survivor.
One day, Morgan encounters a woman named Ruth who claims to be immune to the plague. As he gets to know Ruth, Morgan begins to suspect that she may be more than she seems. He begins to question whether the vampires are really his only enemy, and whether he is truly the last man on earth.
The Last Man on Earth is a classic science fiction film that explores themes of loneliness, survival, and what it means to be human. Despite its dated special effects and low budget, it remains a compelling and thought-provoking film.
