When a dog shows up in camp, some of the prisoner want to keep the animal as a pet. They even tell Schultz that the dog belongs to a German General who will pay a handsome sum to get the dog returned.
In the meantime, new German tanks are passing the camp and Hogan want to get some pictures of them to relay to London. Carter is assigned the duty of taking the pictures but somehow leaves the camera by the fence. Klink finds the camera, that contains no film, and suspects that Hogan is behind the violation.
With a search going on, Hogan places the film inside the dog's bone. The problem is the dog buries the bond and no one knows the location.
Seems kind of strange that someone that is secretly taking pictures would have time to remove the roll of film at the site and leave the large camera behind. It just did not make sense. Nor did Hogan trying to sneeze out a code-name while in the presents of Klink and Burkhalter. I know we have to accept some items for TV sake but this episode was nearly beyond-the-pale. But there was enough interest to hold the viewer's attention to the very end.
