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.

Peter and Greta are invited to the Brahms' country house in Connecticutt for the weekend along with backstabbing office rival Wally Frick and his wife Vera. Peter sees an opportunity to discuss an ad campaign with Mr. Brahms but Greta has a date with Bernie, which she reluctantly breaks. Wally and Vera do their conniving best to foil Peter, meanwhile Bernie has found out where Greta is and shows up at the Brahms'. Greta and Peter let him in a bedroom window and tell him Peter is her brother who has violent tendancies and that they are really at a rest home. Bernie leaves and the others hear an intruder. Figuring it's Bernie, Peter rushes out, makes it sound good and sends Bernie on his way. He succeeds in impressing Brahms but later faints when he finds out the police caught the real prowler, an escaped convicted murderer

Peter accepts a job with another company where his advancement won't be hindered by being a bachelor. He writes a scathing letter to Mr. Brahms exposing the entire setup with Greta. He then goes home and tells Greta their occasional marriage is over. Peter finds out the next day that the man who hired him has been let go, so he's not hired. Peter goes through the mail in Mr. Brahms' office but doesn't have time to get his letter back so he ends up hiring a shady character to break into the office with him and retrieve it. He then has to renegotiate the terms of Greta's employment before she'll agree to continue their ""marriage"".

Peter's mother wants them to re-enact their ""marriage"" in a church so Greta and Peter hire an actor to ""marry"" them. Peter's mother also brings along her own minister just in case, as well as inviting Mr. and Mrs. Brahms and others to the ceremony. The actor, Frank Mastin, gets stage fright and is late, leaving worries that the real minister might perform the wedding. Mastin's agent reminds him of the animated movie he did and after he starts the ceremony he forgets his lines but continues with the ones from the movie in which he married Mr. Bear and Miss Antelope. Peter's mother loves the service and hires the ""minister"" to perform a future wedding for Peter's cousin. The man-in-the-middle tries to hang a picture as the action ensues.

Mr. Brahms summons Greta to his office in order to surprise her with the news he is promoting Peter and giving him a raise and asks Greta to have Peter call him later that evening. Greta tries to do so but Peter is busy romancing Ginger Snap in his apartment and ignores her attempts. Peter finally gets the message after again renogiating his deal with Greta. The next day at Peter's new office Ginger shows up looking for an earring and gets the job as Peter's secretary. Then, in walks Greta and Ginger finds out he is married. Ginger and Greta become friends and Peter is literally left holding the grocery bags. On one fire escape trip Peter and Greta pause long enough to each take a sip from the man-in-the-middles coffee cup.
