It has been six months since the death of Grandpa, and Simon is living with Grandma. He has lost his presenting career and London flat, but is now set to act in a low-key BBC comedy.

Tanya and Liz haven't spoken to each other since their father's funeral, and Grandma makes an underhanded attempt at bringing them back together. Meanwhile, for the sake of the reunion, man-of-the-house Simon needs to get rid of an interesting young visitor and an uncomfortably persistent Clive.
