Sylvester Stallone and Arnold Schwarzenegger team up to bust out of a futuristic jail. Stallone headlines as a "structural security expert" whose job it is to test out prison facilities. But when he's double-crossed and dumped in a freaky, high-tech facility, he's got to use all his skills to escape. It's silly B-movie exploitation, but like the boys' recent team-ups in The Expendables movies, this one's well aware of its tone. 116 minutes R.
