Invasion of the Body Snatchers

A doctor in a small California town whose patients are becoming hysterical and accuse their loved ones as emotionless imposters. Plant-like extra-terrestrials have invaded Earth, replicating the villagers in giant seed "pods" and taking position of their souls while they sleep. Realizing that the epidemic is out of control, in a terrifying race for his life, he escapes to warn the world of the deadly invasion of the pod people.
