"A science fiction horror fable… it may be the best film of its kind ever made!" – Pauline Kael, The New Yorker
Under cover of darkness, while an unsuspecting city sleeps, an alien life form begins to sow the seeds of unspeakable terror. Donald Sutherland, Brooke Adams, Leonard Nimoy, Veronica Cartwright and Jeff Goldblum star in this shocking, "first-rate suspense thriller" (Newsday).
One by one, the residents of San Francisco are becoming drone-like shadows of their former selves. As the phenomenon spreads, two Department of Health workers, Matthew (Sutherland) and Elizabeth (Adams), uncover the horrifying truth: Mysterious pods are cloning humans — and destroying the originals! The unworldly invasion grows stronger with each passing minute, hurling Matthew and Elizabeth into a desperate race to save not only their own lives, but the future of the entire human race.
