Abel Ferrara's Body Snatchers is the third screen version of Jack Finney's cold war science fiction novel Invasion of the Body Snatchers. Marty Malone is moving with her father, stepmother, and stepbrother to a military base where her father will investigate possible environmental and ecological problems. Before they get to town, Marty is warned in a gas station restroom by a crazed looking military man that, "They get you when you sleep!" Marty adjusts to life on the base by flirting with a young officer and making friends with the rebellious daughter of the base commander. These friends help her when a plot by aliens to turn all humans into unemotional, unfeeling "pod people" shifts into high gear. As her family and friends are attacked, Marty doesn't know who to trust.
