Peter and Greta set up housekeeping and purchase a wedding ring. They hold a wedding reception at Peter's apartment and just before Mr. Brahms and the guests arrive his girlfriend Marilyn appears. Peter whisks her upstairs to Greta's apartment via the fire escape. The man-in-the-middle is watching a romance movie on TV but eventually shuts it off in favor of the fire escape action. Peter and Greta successfully pull off the reception despite a few small slip-ups and a drunken Marilyn showing up, who they pass off as Peter's sister. Greta leaves to go on a date but Peter's mother calls, she's just heard he was married and wants to meet Greta which sends Peter up the fire escape calling for Greta.

Peter's mother sees Greta kissing another man and confides in Mr. Brahms, who hires detective Will Yates. Peter's secretary Miss Wilson tips him off to the situation. Greta refuses to give up her date that night so they go to a movie where they plan to ditch Yates, who sits behind them. The next day he goes to Greta's apartment and tells Greta he knows the truth and wants money to buy his silence. Peter finds out Yates has a jealous wife and he and Greta try to get Yates in a compromising photo. This involves a last minute discovery that Peter's camera is out of film and a druggist who has a difficult time counting. The man-in-the-middle views the action while playing poker with a friend who cheats.
