When one of the prisoners, that was sent on his way to be picked up by the underground, is captured by the Gestapo- Hogan believes that there is a leak in the chain of the underground network. In order to reveal who in the chain is leaking the information to the Germans, Hogan is going to take the escape route himself.
With the help of a forest fire, thanks to Carter, it will distract Klink so that he will send a work detail out to the woods. While in the woods, Hogan, LeBeau and Newkirk, will take the route which begins at the Hauserhof and meet two female contacts at that point. Next they will go a farmhouse where Hogan will find that the leak is somewhere along those points. The Gestapo is on their way.
The story was very interesting and played out fairly well. Some of the parts fell into place much too easy which did not seem correct even for this sitcom. But overall the viewer was treated to a nice half hour of comedy. A good watch.
