Lt. Jim Reardon: Colonel, I've been watching these Nips. There's never more than a handful of 'em guarding the perimeter at any given time. And they're not watching very closely. It just doesn't make sense to me unless... McLean: Unless what? Dr. Coates: Well, unless every prisoner's been caught or died in a thousand miles of hostile jungle. Unless the local villagers are willing to turn in a POW for a bowl of rice. Unless - escape is impossible.
