Lifeforce

The Anglo-American space shuttle Churchill rendezvouses with Halley’s Comet. The crew are amazed to find a two-mile long spaceship in the head of the comet and inside it hundreds of human bodies in suspended animation. But the return mission goes wrong and only the three bodies brought back from the spaceship as specimens survive. Examiners are startled when these bodies return to life and turn on humans, sucking out their lifeforces to leave the victims withered, desiccated corpses. Impervious to bullets, the aliens walk out into the streets to claim more victims, but then the victims return to life infected with the desperate need to devour lifeforce too lest they disintegrate into dust. The outbreak reaches nightmare proportions and the whole of London is placed under military quarantine. Meanwhile the Churchill’s commander Tom Carlsen returns in an escape pod. He has developed a strange psychic link with the female alien and sets out to hunt her down as she moves through a succession of host bodies.
