Invasion of the Body Snatchers

“The seed is planted... terror grows.”

Matthew Bennell (Donald Sutherland), a San Francisco health inspector, wants an explanation for why Elizabeth Driscoll (Brooke Adams) says her boyfriend has stopped being himself. Soon more people around the city are acting the same way, flat and obedient, as if the original person had been replaced by a drone. Philip Kaufman follows Matthew and Elizabeth as the only people who notice, and the number of people they can trust keeps shrinking.
