When their house is subject to a compulsory purchase order the Ropers must move.
Mildred sees her dream house in suburbia, next door to yuppie couple Ann and Jeffrey Fourmile and their seven-year-old son Tristram.
Jeffrey is appalled by George and pretends the house is already sold to prevent him and Mildred moving in but Tristram explains that his dad is lying and the Ropers get the house.
