With Edith and Phil’s sunset future in suspense, Phil’s beginning to despair of ever selling his house. Queenie talks him into an Open Day – but with ulterior motives.

After his disastrous Open Day, Phil has disappeared. As Edith searches for him, her difficult sister Joan invites herself to stay. Meanwhile Roger comes up with a new way to make money: by renting out his mother's spare room online, to two Americans.

Edith is finding her irritating sister Joan very difficult, and Roger, impatient to help Phil sell his house, decides to help by checking his roof for dry rot.

Edith and Phil are dismayed to find themselves portrayed in Wendy’s prizewinning book, and Roger’s hopes of becoming a carer look like being revived.

Edith and Phil can finally make a plan for their wedding – which doesn’t include an invitation for Bob – and Roger enlists Georgie to video the proceedings.
