Lifeforce is a 1985 British science fiction horror film directed by Tobe Hooper, written by Dan O'Bannon and Don Jakoby, and starring Steve Railsback, Peter Firth, Frank Finlay, Mathilda May, and Patrick Stewart. Based on Colin Wilson's 1976 novel The Space Vampires, the film portrays the events that unfold after a trio of humanoids in a state of suspended animation are brought to Earth after being discovered in the hold of an alien space ship by the crew of a European space shuttle.
The film received negative reviews on release and was a box office failure, but has since become a cult film.
Plot[]
The crew of the joint British and American space shuttle Churchill, under the command of Colonel Tom Carlsen, finds a 150-mile-long spaceship hidden in the coma of Halley's Comet. Inside, the crew discovers hundreds of desiccated bat-like creatures and three naked humanoid bodies (two male and one female) in suspended animation within glass containers. The crew recovers a bat-alien and the three bodies and begins the return trip to Earth. However, during the return journey, mission control loses contact with Churchill. A rescue mission is launched to investigate.
The rescuers discover that Churchill has been gutted by fire. The present crew are dead, and the escape pod is missing, yet the three containers bearing the bodies remain intact. The bodies are taken to the European Space Research Centre in London. Prior to an autopsy, the female alien awakens and drains the life force out of a guard. She then escapes the facility and proceeds to drain other humans of their life force, revealing an ability to shapeshift. The guard revives after two hours and also displays the ability to drain others of their life force. Soon thereafter, the two male vampires awaken and attempt a violent escape, but they are apparently destroyed by grenades thrown by the guards.
Meanwhile, in Texas, an escape pod from Churchill is found with Carlsen inside. Carlsen is flown to London, where he describes the course of events, culminating in the draining of the Churchill crew's life force. Carlsen explains that he set fire to the shuttle with the intention of saving Earth from the same fate and escaped in the pod. However, when he is hypnotised, it becomes clear that Carlsen possesses a psychic link to the female alien. Carlsen admits to Caine that, while on Churchill, he felt compelled to open the female vampire's container and share his life force with her. Carlsen and SAS Colonel Colin Caine trace her to a psychiatric hospital in Yorkshire. The two believe they have managed to trap her within the heavily sedated body of the hospital's manager, Dr. Armstrong. Carlsen and Caine later learn they were deceived, as the aliens had wanted to draw them out of London.
The two male vampires have survived by shapeshifting into the soldiers who killed their previous bodies, and now the pair are infecting most of London's population. As Carlsen and Caine are transporting Dr. Armstrong back to London, the female alien escapes from her sedated host and disappears. Martial law is declared as the vampire plague sweeps through the city; the victims seeking out other humans to absorb their life force and perpetuate the cycle. The absorbed life forces are channeled by the male vampires to the female vampire, who transmits the accumulated energy to their spaceship, which is now in geosynchronous orbit over London.
Dr. Fallada impales one of the male vampires with an ancient weapon of "leaded iron". He contacts Carlsen and Caine and surmises that the creatures have visited Earth periodically with the coming of Halley's Comet, creating the vampire legends. He delivers the weapon to Caine before succumbing to the infection. The female vampire is tracked by Carlsen to St. Paul's Cathedral, where she is lying upon the altar, transferring energy to her spaceship. She reveals, much to Carlsen's shock, that they are a part of each other due to the sharing of their life forces, thus sharing their psychic bond. Caine follows Carlsen to the cathedral and is intercepted by the second male vampire, whom he kills. Caine throws the weapon to Carlsen, who impales himself and the female alien simultaneously. This action causes the release of a burst of energy that blows open the dome of St. Paul's. The two ascend the column of energy to the spaceship, which then returns to the comet as Caine watches.
