The Heroes are harboring a prisoner who has stolen valuable maps to be delivered to the Underground. As he is about to leave, Klink is seen prowling about the grounds, unable to sleep. He confides in Hogan that he feels like a failure and that Gen. Burkhalter is going to visit and discuss his future. The general says that he does not like the fact that Klink is single. He says that one of the members of his graduating class just made general because he married a field marshal's niece. As he leaves, he says he will bring his sister and niece to visit. Klink thinks that Burkhalter wants him to marry his niece, and he doesn't like it because she may look like her uncle.
However, she is a beautiful girl; her mother, however is not. Klink wants to woo the niece, Lotte, and asks Hogan for help. But, Burkhalter wants Klink to marry his sister, Gertrude. She asks Klink personal questions and he gets help from Hogan. He composes a letter saying that Klink wants to ask an important question. He delivers it to Lotte, but she says that it is her mother that wants the marriage because her husband is MIA at the Russian Front. Eventually, Klink finds out the truth, and Hogan bails him out by saying he has volunteered for the Russian Front. Gertrude calls off the wedding and Klink says he will sleep well.
