The kidnappers tie up the wealthy young people and leave them completely unattended for long periods of time. So, guess what? One of them wriggles out and they escape. I believe in suspension of disbelief for a good story, but this isn't one of them. I would have preferred that Ray Liotta went berserk and rescued the victims. I also hated the lead character's narration. Don't say it, show it. The ends did not justify the means.
