George and Mildred go house hunting and find their dream house in an up market part of town but their neighbours (the Fourmiles) do not want them to move in. Jeffery Fourmile pretends that the house has been sold until the Ropers find out the truth.

The Ropers finally move into their new house and to help things along Ann Fourmile invites them in for afternoon tea. When they get back home they find themselves locked out and the bath water running away.

George is talked into getting a job, however...Mildred winds up getting that same job instead.

After babysitting for the Fourmiles, Mildred begins to feel maternal-like. She tries to convince George to adopt a baby but instead they settle for a puppy.

Mildred discovers that George has no insurance when a relative dies and the funeral costs are overwhelming. Jeffrey decides to cover the costs but then George changes his mind...

George finally sells his old car and buys a trashy old caravan. He dumps it on the front lawn and when Mildred's pesky sister and brother-in-law visit, they stay in the Roper's room so a stubborn George stakes out in the caravan. That is, until it is towed away.

George tries to cover up the fact that he lost Mildred's puppy by replacing it with a look alike but all goes awry when the police bring home the original dog.

George threatens to sue when Jeffrey accidentally causes him to fall by moving the ladder as George attempts to fix the TV aerial.

While the Fourmiles are away, George and Mildred decide to get their house decorated by professionals...but the interior designers accidentally redecorate the Fourmiles house...so George and Mildred must fix it before the Fourmiles return.

Mildred's mother visits, but the family decide she is too old to look after herself and decide to place her in a home, however, George unexpectedly takes Mildred's mothers side and asks her to stay with them.
