Susan has got a job as a door to door saleswoman. Selling a multi appliance brush.
Freddy (George Layton) is showing her the ropes and he thinks Susan is a natural saleswoman.
When Freddy and his pregnant wife Ann (Patricia Brake) stay over at the flat. Dudley thinks that his 17 year old daughter is up to no good. Even if Freddy does look normal.
The plot is a sitcom staple of mistaken intentions. Susan has not told her parents of her latest job.
Susan and Jacqui has also decided not to tell their parents about Freddy and Ann staying over.
It is a weak plot. Once again it is left to Robert Gillespie to provide the zaniness.
The episode opens with Dudley making a false radio news broadcast. Then he is trying to give up smoking with diffulties.
