Lenny's mother is coming to stay at Hotel Trubble. Lenny is only a porter but he has told his mother that he owns the hotel and so efforts are made to deceive her, efforts which, inevitably, come unstuck although she has had her suspicions all along.
A priceless jewel has been deposited in the hotel to await Mr. Trubble and all the staff are keen to take a look at it. It is on the cards that someone will try to steal it and an agent has come to protect it. However, he is not who he says he is and it's a good job that Mrs.Poshington is well-versed in the martial arts.
Mr. Wreck and Mr. Ball come to Hotel Trubble saying that they have orders for its demolition. The staff go on the streets with a petition and record a charity single in the hopes of preventing the demolition but it looks as if their efforts will fail. Fortunately Mrs. Poshington has the sense to study the demolition order closely and discovers that it's for the building next door.
