Invasion of the Body Snatchers | 1978
Strange spores fall from the sky in San Francisco, which take root and eventually fill the city with plants that bear spectacular flowers. But what the population does not know is that these extraterrestrial plants have come from a dying planet to earth with a purpose. They also produce pods that replicate each human being, who is then killed and replaced by their clone. Once the populace realizes what is happening, the remaining humans try to escape this doom, unable to know who they can trust as they do so.
