| Synopsis | Citizens are very concerned that the Presby brothers haven't been seen in over 25 years, so the boys and the Guardian investigate, only to learn that they locked themselves in their home to avoid contact with World War 1 and now World War 2. However, that plays right into the hands of a couple of Nazi spies who intend to use their home as a secret Nazi radio station to contact submarines. |
