The story tells about the high end technology in the near future. everybody has their own surrogates while the real self can be stayed at home, controlling and watching every movements and actions by their own surrogates. agent Tom Greer (Bruce Willis) takes the mission to stop the operation on destroying every surrogates.
its amazing to see what graphics and computers can do these days. however, the story is abit dull in the beginning. the climax is almost towards the end of the movie..
