When LeBeau, Carter and Newkirk are caught by the Gestapo, after blowing-up a train, they, with their false names, are sent to Stalag 4 for interrogation. When Hogan is told of the capture, he immediately plans a way where they can be freed. But it is going to consist of making Schultz a Colonel.
In a strange way, Hogan gets Schultz to believe that the three captured Heroes are going to tell the Gestapo all about Schultz's actions at Stalag 13. So Schultz is now ready to get the three men back at any cost. The cost will include posing as Colonel Klink and going to Stalag 4 to rescue the prisoners. But is Schultz going to be able to fool the Commandant of Stalag 4?
Even though this is a TV sitcom, there does have be some reason of justification into each action of a character. This episode stretched the imagination of everyone involved. But guessing we are watching just for a good time, then this show delivers. Not the best written script but one that was enjoyable enough to watch.
