Lifeforce (film)

Lifeforce is a 1985 science fiction, horror film directed by Tobe Hooper and written by Dan OBannon and Don Jakoby, based on Colin Wilsons 1976 novel, The Space Vampires. Featuring Steve Railsback, Peter Firth, Frank Finlay, Mathilda May, and Patrick Stewart, 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 abandoned European space shuttle. The film received mixed to positive reviews, and was a box office bomb.

During the return journey, mission control loses contact with the shuttle and a rescue mission is launched to investigate. The rescuers discover that the Churchill has been severely damaged by fire, with its internal components destroyed, and the three containers bearing the aliens are all that remain intact. The aliens are taken to the European Space Research Centre in London where they are watched over by Dr. Leonard Bukovski Gothard and Dr. Hans Fallada Finlay. Prior to an autopsy, the female alien May awakens and drains the life force out of a guard. The female alien then escapes the research facility and proceeds to drain various other humans of their life force, revealing an ability to shapeshift. It transpires that the aliens are from a race of space vampires that consume the life force of living beings, rather than their blood.Meanwhile, in Texas, an escape pod from the Churchill is found, with Colonel Tom Carlsen Railsback inside. Carlsen is flown to London where he describes the course of events, culminating in the draining of the crews 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 hypnotized, it becomes clear that Carlsen possesses a psychic link to the female alien. Carlsen and SAS Col. Colin Caine Firth trace the alien to a psychiatric hospital in Yorkshire. While in Yorkshire, the two believe they have managed to trap the alien within the heavily sedated body of the hospitals manager, Dr Armstrong Stewart but Carlsen and Caine later learn that they were deceived, as the aliens had wanted to draw the pair out of London. ........
