But things happen. Rockwell is injured, and when he wakes up, well, I probably shouldn't say. In fact, anything else I tell about the plot would pretty much spoil it for you, so I'll just say nothing.
What I will say is that this is an SF movie with no explosions, no aliens, no monsters. There is, however, an evil corporation. Is there any other kind? I eagerly await a good SF movie about a beneficent corporation. Where was I? Oh, right. It's a very quiet movie that has some interesting points to make about identity and what it is to be human. Rockwell has a big load to carry, and he does a fine job. I can see why he'd want to make the film. And Kevin Spacey gives great voice. Check it out.
