George Clooney stars in Steven Soderbergh's version of Stanislaw Lem's classic sci-fi novel. Chris Kelvin (Clooney) is a psychologist sent to investigate a series of mysterious occurrences aboard a distant space station. When he arrives he finds the two surviving crew members isolated from each other, and he learns that they have both received visits from loved ones who have been dead for many years. Soon Kelvin receives a visitor of his own - a figure in the form of his dead wife Rheya (Natascha McElhone) - and the feelings of guilt and tenderness that she awakens in him make his attempts to penetrate the mystery even more difficult. Lem's novel was previously filmed in 1972 by the great Russian director Andrei Tarkovsky.
