When the POWs learn from their radio that there is to be a massive air raid in their area, they decide that it would be the perfect time to use their tunnel for the mass escape. They push to finish the last few yards into the woods but a cave-in seemingly ends their hopes of escape. Until, that is, Drew Pritchard comes up with a brilliant idea. It's also left to Pritchard to steal a travel pass from the Kommandant's office. When he is caught, Commandant Dreiber is prepared to use whatever means necessary to find out what is going on.
