The film, billed as “a love story rich with emotion and mystery,” takes place in the future on a space station orbiting the unique planet Solaris, which is being studied by a crew of four scientists. When widowed psychologist Chris Kelvin (George Clooney) arrives, he finds that one crew member is missing and another has committed suicide. The remaining two scientists show symptoms of anxiety and paranoia. Other strange events begin to occur, including Dr. Kelvin’s vivid interactions with what appears to be his long-deceased wife (Natascha McElhone). He must distinguish what is reality as he seeks to help the crew.
